Q. Luke can paint

91

portraits in

7

weeks. How many portraits can Luke paint in

4

weeks?

Identify Unit Rate: Identify the unit rate of portraits painted per week. $\newline$ To find out how many portraits Luke can paint in one week, we divide the total number of portraits by the total number of weeks. $\newline$ Calculation: $91$ portraits $\div$ $7$ weeks = $13$ portraits per week.
Calculate Weekly Total: Calculate the number of portraits Luke can paint in $4$ weeks. $\newline$ Now that we know Luke can paint $13$ portraits in one week, we multiply this unit rate by the number of weeks in question. $\newline$ Calculation: $13$ portraits per week $\times 4$ weeks = $52$ portraits.
