Fill in the following blanks : [Are these equivalent ratios?]

Explanation

`15 / 18` =`square / 6 `= `10 / square`= `square/ 30`

`15 / 18 = (5 xx 3) / (6 xx 3)`
=` 5 / 6`
`5 / 6 = (5 xx 2) / (6 xx 2)``= 10 / 12`
`5 / 6 = (5 xx 5)/(6xx5)``=25/30`
Hence, 5, 12 and 25 are the
numbers that come in the blanks, respectively.
Yes, all are equivalent ratios.
