Question

One box contains $6$ cookies and there are $7$ such boxes of cookies. If the cookies are equally distributed among $3$ plates, what will the number of cookies on each plate be?

• A. $25$
• B. $14$
• C. $20$
• D. $10$

Answer 1

The correct option is B $14$

Number of cookies in one box $=6$
Total number of boxes $=7$
Total number of cookies = total number of boxes $\times$
number of cookies in one box
$=7\times 6=42$ cookies

$42$ cookies are equally divided among $3$ plates.
Total number of cookies $=42$

Number of plates $=3$
Number of cookies on each plate = total number of cookies $÷$ number of plates
$=42÷3$
We will use the area model to divide $42.$ Let’s split $42$ into tens and ones as shown below.
$42=30+12.$



Number of cookies on each plate $=42÷3=(30+12)÷3=(30÷3)+(12÷3)$
$=10+4=14$

There will be $14$ cookies on each plate.
