Question

Factor out the coefficient of the variable in the expression 1/3b - 1/3

Answer 1

`(1)/(3) \left ((1)/(b) - 1 \right )`

Explanation:

`f(x) = (1)/(3b) - (1)/(3)`

1. Find the least common multiple of the denominators

The least common multiple of 3 and 3 is 3.

2. Factor out ⅓.

`(1)/(3b) - (1)/(3) = \mathbf{(1)/(3) \left ((1)/(b) - 1 \right )}`
