• True

• False

When adding and subtracting rational expressions, my first step should be to:

• Combine like terms in the numerators.
• Determine a Least Common Denominator.
• Factor all of the numerators and all of the denominators.
• Change the operator to multiplication and reciprocate the second fraction.

Simplify the expression

• (2a + 4b) / 12b²

• (2a - 4b) / 12b²

• (a - b) / 6b²

• (a + 2b) / 6b²

Simplify the expression

• n / 2m

• n / 3m

• (m² + 4n²) / 12m

• n / 4m

Simplify the expression

• 6x / 20xy

• 3 / 10y

• (6x+1) / (20xy)

• 3 / 20xy
