Question

4 2/5 * 7 1/8 A. 176/285 B 28 1/20 C 31. 7/20 D. Not given

Answer 1

`31(7)/(20)`

Step-by-step explanation:

Given the product

`4(2)/(5)\cdot7(1)/(8)`

Convert the mixed fractions to proper fractions.

`\begin{gathered} 4(2)/(5)=(4\cdot5+2)/(5)=(22)/(5) \\ 7(1)/(8)=(7\cdot8+1)/(8)=(57)/(8) \end{gathered}`

Find the product.

`(22)/(5)\cdot(57)/(8)=(627)/(20)`

Convert to mixed fraction.

`\begin{gathered} (627)/(20)=(31\cdot20+7)/(20) \\ =31(7)/(20) \end{gathered}`

Option C is correct.
