The area of a rectangle is A=lw. A is the area, l is length, w is width. So, you just need to multiply length times width to get area. BUT, you have the area--what you need to find is length. Let's fill in what you know so far. 120 1/4 = l * 6 1/2.
But to find the length, you need to isolate it on one side of the equation. So, you can divide both sides by 6 1/2. l * 6 1/2 / 6 1/12 = 120 1/4 / 6 1/2. So, l <span>= 120 1/4 / 6 1/2.
Now, we just need to calculate 120 1/4 divided by 6 1/2. The first thing to do when dividing fractions is to convert all fractions into improper fractions. We need to turn 120 1/4 into an equivalent fraction, with 4 as the denominator (bottom number). How do you do that? Multiply 120 by the denominator, 4, and put this as the numerator to get 120*4 / 4 or 480/4. We know this is true because if you divide 480 by 4, you get 120, so this is an equivalent fraction. Finally, we need to add the numerators 480 and 1 together, because they are part of the same number and have the same denominator. So, 120 1/4 = 481/4.
Same concept with 6 1/2: 6*2=12, 12+1=13, answer is 13/2.
Next, when dividing fractions, you multiply by the reciprocal. So, since you're dividing 481/4 by 13/2, that's the same as multiplying by the reciprocal of the divisor, 13/2. The reciprocal is basically the opposite of the fraction, where you switch the numerator and denominator. The reciprocal of 13/2 is 2/13. Now you just need to multiply 481/4 by 2/13.
Remember, when multiplying fractions, you multiply numerators together to get new numerator, and multiply the denominators to get the new denominator. 481*2=962, and 4*13=52. The answer is 962/52.
After that, you need to simplify this by finding their greatest common factor and dividing by it. The GCF is 26. 962/26=37, and 52/26=2. So, the answer is 37/2. Finally, you need to convert this back to a mixed number. 37/2 = 36+1 / 2 = 36/2 + 1/2 = 18 1/2. Since the area is in square inches, the length must be in inches.

Answer:
The question you asked is different from the image. So, I'll give you two answers to choose from.
Question you asked: Percentage of male students = 56.25%
Question from image: Percentage of female students = 43.75%
Step-by-step explanation:
A total of 32 students is 100%.
14 of them are female.
Divide 14 by 32 to get 0.4375 or 43.75%.
Subtract 100% by 43.75% to gain the percentage of male students.
Answer is 0.5625 or 56.25%.
The answer is 140
140 x 0.1 (10% as a decimal) = 14
