Question

A school has ordered 400 notebooks for pre k students and 600 notebooks for grade 1 students. How many books have been ordered altogether? Express in the form of repeated multiplication.

• A. 10 $\times$ 10 $\times$ 10 $\times$ 10
• B. 10 $\times$ 10 $\times$ 10 $\times$ 10 $\times$ 10 $\times$ 10
• C. 10 $\times$ 10 $\times$ 10 $\times$ 10 $\times$ 10
• D. 10 $\times$ 10 $\times$ 10

Answer 1

The correct option is D 10 $\times$ 10 $\times$ 10

Total number of notebooks = 400 + 600

= 1000

= 10 $\times$ 10 $\times$ 10

Hence, the total number of books in repeated multiplication form is "10 $\times$ 10 $\times$ 10".
