Find the common denominator
Can you clarify your question?
Answer:
<h2>5(2a - 5 + b)</h2>
Step-by-step explanation:
10a = 2 · 5 · a
-25 = -5 · 5
5b = 5 · b
GCF(10a, -25, 5b) = 5
The distributive property: <em>a(b + c) = ab + ac</em>
Therefore
10a - 25 + 5b = 5 · 2a - 5 · 5 + 5 · b = 5 · (2a - 5 + b)
A whole number because 45 divided by 9, a whole number.
