Question

A bit rusty on multiplying fractions with whole numbers.

Answer 1

69 3/10 square meters

Step-by-step explanation:

Given the expression:

`16(1)/(2)*4(1)/(5)`

First, change each mixed fraction to an improper fraction:

To change a mixed fraction, multiply the denominator by the whole number, add the numerator:

`\begin{gathered} 16(1)/(2)=(2*16+1)/(2)=(33)/(2) \\ 4(1)/(5)=(5*4+1)/(5)=(21)/(5) \end{gathered}`

Thus, the expression becomes:

`=(33)/(2)*(21)/(5)`

Next, multiply the numerators and denominators:

`\begin{gathered} =(33*21)/(2*5) \\ =(693)/(10) \\ =69(3)/(10)m^2 \end{gathered}`
