Answer 2

Answer:

For 15 ballons    

Since 20 balloons = 15 minutes

15 balloons =  

cross multiply

225/20

= 11.25

minutes

for 6 ballons

Since 20 balloons = 15 minutes

6 balloons =

90/20

= 4.5  minutes

For 45 balloons

45 balloons =

45 × 15 /20

675/20

33.75  minutes

Explanation:

Fred the clown can create 20 animals balloons for every 15 minutes. Let us calculate the rate at which he can make the balloons.

Since he makes 20 balloons for 15 minutes

he will make ? balloons for 1 minutes

cross multiply

20/15 = 1.333 minutes

The question ask to use equivalent ratios minutes number to calculate for 15 , 6, and 45 ballons

For 15 ballons    

Since 20 balloons = 15 minutes

15 balloons =  

cross multiply

225/20

= 11.25

minutes

for 6 ballons

Since 20 balloons = 15 minutes

6 balloons =

90/20

= 4.5  minutes

For 45 balloons
