Question

Fill in the blanks!

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 = _

Answer 1

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**
