Answer:
a:b
2:5
Step-by-step explanation:
a/2 = b/5
Divide each side by b
a/2b = b/5b
Multiply each side by 2
2a/2b =2b/5b
a/b = 2/5
The ratio of a to b ( or a/b) is 2/5
5a = 2b
a:b = 2:5
the answer is b because the rate would not change
change it to 5 4/16 then change it to 20/16 then subtract 7 and 13/16 so 5 13/16
< 6
