HELP Which of the following is a true statement?
4/5 x 4/5=1
3/10 ÷ 7/9=3/10 x 9/7
9/12 x 12/9= 0
1/2 ÷1/2= 1/4

3/10 ÷ 7/9=3/10 x 9/7 is the true one

Step-by-step explanation:

4/5 x 4/5 = 16/25 not 1 so this statement is wrong.

3/10 ÷ 7/9=3/10 x 9/7, this is the true statement and it equals 27/70

9/12 x 12/9= 1 not 0

1/2 ÷1/2= 1 not 1/4

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

the answer is 5/14.

hope this .
