Question

liam practiced piano 24 times in 4 weeks. his brother practiced piano 12 times in 14 days. are the rates at which each brother practiced equivalent?

Answer 1

Yes because if you simplify 24 and 4 weeks(28 days) by 2 than you would get 12 and 2 weeks(14 days)

Answer 2

the rates are equivalent.

Explanation:

liam practiced piano 24 times in 4 weeks.

1 week = 7 days

4 weeks = 28 days

liam practiced piano 24 times in 7 days

The ratio of 24 times to 7 days is
`(24)/(28)`=
`(6)/(7)`

his brother practiced piano 12 times in 14 days.

The ratio of 12 times in 14 days is
`(12)/(14)`=
`(6)/(7)`

Both the fractions are equivalent

So the rates are equivalent.
