Question

The ratios 3/5 and 15/30 are written on the whiteboard. Are the ratios equal?

Answer 1

No

Explanation:

to change the denomiator from 5 to 30 you have to multiply by 6

if you multiply the denominater by 6, you also have to multiply the numerator by 6

so,
`(3)/(5)=(18)/(30)`

`(18)/(30)\\eq (15)/(30)`
