Question

Write three ratios equal to 7/35? A 1/7, 2/14, 3/21 B 5/7, 10/7, 15/7 C 7/35, 7/40, 7/45 D 1/5, 2/10, 3/15 I think it is C or D.

Answer 1

The answer is actually D because 7 and 35 divided by 7 are 1 and 5.

Answer 2

`(1)/(5) ;(2)/(10) ;(3)/(15)`

Explanation:

To find the three ratios we only have to find the most simple ratio of
`(7)/(35)`, and then find the other ratios that are equal to it.

So,
`(7)/(35) = (1)/(5)`

Also,
`(1)/(5) =(2)/(10)`, by multiplying by two each part of the fraction.

Similarly,
`(3)/(15) = (1)/(5)`, by multiplying by three.

Therefore, comparing all these ratios, all are the same, they are equal to
`(1)/(5)`. So, the option that correctly has these choices is D.
