true or false ratios

7/9=56/72
10/13=140/180
16/9=192/108
10/1=1/10

Answer 1

write each pair in lowest terms.

7/9 is already in lowest terms 56/72 has 8 as GCF - so divide 56 and 72 by GCF
56/72=7/9

the ratio 7/9=56/72 is correct

Answer 2

10/13 is also already in lowest terms.
140/180 have 20 as GCF. so the 140/180=7/9

this ratio is false

Answer 3

16/9 is already in lowest terms
192 and 108 have 4 as GCF. so 192/108=48/27. This ratio is false

Answer 4

10/1 is equal to 10
1/10 is not equal to 10, so this ratio is also false

Answer 5

only A is correct.
