When two numbers in an addition expression share a common factor, you can write the expression as a multiplication expression.

Sum:
10 + 15 = _
Factors of 10: 1, 2, 5, 10
Factors of 15: 1, 3, 5, 15
GCF of 10 and 15: _

Equivalent expression:

10 + 15
5 (_) + 5(3)
_ (2+3)

Now what we have is an equivalent mutiplication expression to our original addition expression.

10+15 = _ (2+3)
25 = _

Let's fill in the blanks step by step.

Sum: 10 + 15 = 25 Factors of 10: 1, 2, 5, 10 Factors of 15: 1, 3, 5, 15 GCF of 10 and 15: 5

Now, we can rewrite the expression using the common factor:

Equivalent expression:

10 + 15
5 (2) + 5(3)
5 (2 + 3)

Now what we have is an equivalent multiplication expression to our original addition expression.

10 + 15 = 5 (2 + 3)
25 = 25

So, filling in the blanks:

  1. 25
  2. 5
  3. 5
  4. 5
