Question

A bakery uses 10 3/5 ounces of icing for every 1/4 of a cake. What is the unit rate in ounces of icing per cake?

Answer 1

`42(2)/(5)}(ounces)/(cake)`

Explanation:

we know that

To calculate the unit rate divide the total ounces by 1/4 of a cake

but first convert mixed number to an improper fraction

`10(3)/(5)\ ounces=(10*5+3)/(5)=(53)/(5)\ ounces`

`((53/5))/((1/4))=(53*4)/(5)=(212)/(5)(ounces)/(cake)`

Convert to mixed number

`(212)/(5)(ounces)/(cake)=(210)/(5)+(2)/(5)=42(2)/(5)}(ounces)/(cake)`
