Of 140 seventh-grade students, 15% earn the Presidential Physical Fitness Award. How many students earn the award?
Answers
We have an equation: ?/140= 15/100
Cross multiply: 100*?= 15*140 ⇒ ?= 15*140/100= 21
21 students earn the Presidential Physical Fitness Award~
15% is equivalent to the fraction 3/20 so you must divide 140 by 20 then multiply by 3 to get the final answer of 21 students. Hope this helps :D
I have 1/3 of a brownie. If 5/6 of a brownie fills one plate, how many plates can I fill?
Answers
1/3 of a brownie is only 2/6. If it takes 5/6 to fill one plate, then your 2/6 can fill only 2/5 = 40% of one plate.
You can fill two playes because 1/3=2/6 and 2/6 goes into 5/6 twice with 1/6 left over.
