Math CentralQuandaries & Queries


Question from Willie, a parent:

Subtract and express the answer in simplest form. 5x-3/6-x+3/6

Hi Willie,

I think this problem is ractions.

Since the fractions have the same denominator we can write this as ractions. REmoving the parentheses and remembering to distribute the minus sign through the second set of parentheses yields ractions. Now the numerator simplifies to become ractions. But we are not done yet since there is a common factor of 2 in both the numerator and denominator so finally I get ractions.

I hope this helps,
