Explanation:

Answer is 42 2/5

10 3/5 ÷ 1/4 = 53/5 ÷ 1/4

= 53/5 x 1/4

= 212/5

= 42 2/5

Answer 2

Here is a similar question:

A bakery uses 10 1/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake.

The unit rate in ounces of icing per cake = 40 4/5 ounces

Explanation:

Given:

Ounces of ice used for every 1/4 cake = 10 1/5

We have to find the unit rate.

Let the unit rate be 'x' .

Unit rate is the rate when we use unit 'one' as our reference to find any value.

Lets convert the mixed fraction of ounces.

⇒
`10(1)/(5) = ((10* 5)+1)/(5) =(51)/(5)`

Portion of the cake used =
`(1)/(4)`

To find the unit rate here we must divide :

⇒
`x=(number\ of\ ounces\ used)/(portion\ of\ the\ cake)`

⇒
`x=`
`(51)/(5)` ÷
`(1)/(4)`

⇒
`x=`
`(51)/(5)* (4)/(1)`

⇒
`x=`
`(51* 4)/(5)`

⇒
`x=`
`(204)/(5)`

⇒
`x=`
`40(4)/(5)` Or
`40.8`

Hence, the unit rate in ounces of icing per cake = 40 4/5 ounces.
