Question

I need help knowing how to simplify ratios. My test is today.

Answer 1

Part 14

we have

4 in to 7 ft

so

4 in/7 ft

Remember that

1 ft =12 in

so

7 ft=7*12=84 in

the ratio is equal to

4 in/84 in=4/84

simplify

2/42

1/21

answer is 1/21

Part 14

12 cm to 1 m

we have

12 cm/1 m

Remember that

1 m=100 cm

so

12 cm/100 cm=12/100

simplify

6/50

3/25

answer is 3/25
