In math class the girl to boy ratio is 3to 6 if there are 15 girls how many boys are there?
Answers
Another way at looking at it is, for every 3 girls, there are 6 boys or equal to that is a 1:2 ratio. So if there are 15 girls and twice as many guys, there will be 30 guys
proprtions
3 / 6 = 15 / x
so 15 * 6 = 90
divide by 3 and get 30 boys

sonya can walk 12 kilometers in 4 hours. If she has to walk 15 kilometers, how much time will it take her?
Answers
First, We Should Find The Unit Rate... 12 kilometers ------------------ 4 hours We Need To Simplify. 12/4 Can Be Simplified To 3/1. So, 3 kilometers/1 hour is the unit rate. Now, We Need To Change It To 15/X. 15 3 ---- = ---- X 1 Solve For X. To Solve, Multiply Means And Extremes. The Equation Becomes: 3X = 15*1. Simplify. 3x = 15. Now, Divide Both Sides By 3. X = 15/3. 15/3 = 5. X = 5. So, Sonya Can Walk 15 Kilometers In 5 Hours. :D
