Q: A good way to visualize fractions is to draw a picture to represent the fraction you are working with. You can start with any shape you would like, but here we will use a circle. Draw a large circle that you will be able to divide into multiple equal parts. The circle itself is not a fraction. It represents the whole number one. Draw a straight line down the middle of the circle dividing it into two equal pieces. You now have a circle that has two parts that make it a whole. When you are dividing shapes to represent fractions, remember to always divide the shape up evenly so you have equal parts. If you shade one part of the circle, you will have shaded ½ of the circle. The other half remains untouched. Now, draw another straight line horizontally across the center of the circle. The circle should now be divided into four equal parts. You can represent this whole circle as 4/4.  If you shade one piece of the circle, you would have ¼ of the circle shaded. If you shade two pieces of the circle, you would have 2/4 of the circle shaded. Note that 2/4 simplifies to ½. You can also see this visually because you have shaded half of the circle even though it is divided into 4 parts. You can continue to divide the circle into as many equal parts as you would like. Adding two more lines through the quarters will give you a circle divided into eight equal parts. Continue shading parts and writing the fraction that represents the shaded area. Remember, for a circle divided into eight parts, the denominator will always be 8; only the numerator will change to represent the shaded regions.
A: Draw a circle. Cut that circle in half. Cut the circle into four equal pieces. Cut the circle into eight equal pieces.

Article: Your joints and muscles work best when they're warmed up for about 5 minutes. Get your blood flowing by walking at a slow pace on a slight incline, such as at a 2% incline. This will help you avoid injuries such as muscle strains or tears. Follow your run with a few minutes of walking to cool down. Switching up your workout routine will help you keep interest and avoid doing any damage to particular muscle groups. If you focus on speed training and you try to run at a full sprint on 1 day, focus on the distance the next. Sprint for 5 to 20 minutes on your speed day, then jog for 20 to 60 minutes on the next day. Remember to begin and end your workouts with walking to warm up and cool down.  Check your control panel, consult your manual, or talk to a gym trainer to learn about automatic terrain settings that can simulate walking over hills. If you live on flat land but you're training for a race or marathon that'll take place in a hilly area, using terrain training functions can be a great way to build your endurance.
Question: What is a summary of what this article is about?
Warm up your joints and muscles by walking before running. Vary speed and distance training days.

Problem: Article: To pass this portion of the fitness test, do at least 53 sit up repetitions per set if you are between 17 and 21 years old. If you're between 22 and 26, do at least 43 reps. When you train, simply continue the exercise until muscle failure occurs. Repeat until you've completed 4 sets. There should be no more than one minute of rest between each set. If you're able to make it to 72 perfect sit ups, you'll receive a score of 90 points and a rating of "excellent" for this exercise. If you're good at sit ups, work your hardest to receive the highest rating you can achieve.
Summary: Complete the correct number of reps. Train by doing more sets than required. Work toward excellence.

Q: For regular verbs ending in -er, you form the past participle by removing the -er ending and instead using an é. For example, the past participle of parler (to speak) is parlé. For regular verbs ending in -ir, you don't have to remove the entire ending. Just remove the r so that the verb ends with an i. For example, the past participle of the verb choisir (to choose) is choisi. If you have a regular French verb ending in -re, you simply remove the -re ending and replace it with a u to form the past participle. For example, the past participle of vendre (to sell) is vendu. Just as in English, French has a number of irregular verbs that may have endings similar to regular verbs, but are conjugated differently. Their past participles tend to be irregular as well, so you just have to memorize them as you come across them.  In some cases you can find patterns. For example, most irregular verbs that end in -oir have a past participle that ends in u. The past participle of "voir" (to see) is "vu;" the past participle of "vouloir" (to want or to wish) is "voulu." Most irregular verbs that end in -re have a past participle that ends in -is. For example, the past participle of "comprendre" (to understand) is "compris;" the past participle of "apprendre" (to learn) is "appris."
A:
Replace -er with é. Remove the r from -ir verbs. Exchange a -re ending with a u. Memorize irregular verbs.
