Multiply and Divide Within A Hundred 1

Directions: Using the digits 2 to 9 at most one time each, place a digit in each box to make two correct equations: one where the value is greater than 30 and one less than 30. You may reuse all the digits each equation.

Hint

What digits would be better worse to divide by? What are the greatest values you can make on the division side?

Answer

There are many possible answers including 3 x 6 = 72 ÷ 4 (which equals 18 on both sides) as well as 7 x 6 = 84 ÷ 2 (which equals 42 on both sides).

You may reuse all the digits each equation? Is the multiplication and division expressions considered two different equations?

So can we do 2 x 3 = 42/7

23. Mrs. Beatch's Grade 5s

3 x 4 = 72 / 6

answer is 12

24. Mrs. Beatch's Grade 5s

6 x 4 = 72 / 3

answer is 24

25. Ava & Mrs. Hook

1×6=54/9

They both equal 6.
=)

26. One would be 3 x 9 = 54 / 2 = 27, and another could be 7 x 6 = 84 / 2 =42
