Question

How do I solve equations with fractions?

Answer 1

2y - 3/5 = 1/2

• Add 3/5 to both sides.

2y = 1/2 + 3/5

• Let's make the two fractions have common denominators.
• Multiply 1/2 by 5/5 and 3/5 by 2/2.
• 1/2 * 5/5 = 5/10
• 3/5 * 2/2 = 6/10

2y = 5/10 + 6/10

Add the two fractions.

2y = 11/10

Divide both sides by 2.

• 11/10 ÷ 2
• Use the Keep, Change, Flip method.
• Keep 11/10, change ÷ to ×, and flip the 2 (reciprocal).
• 11/10 × 1/2 = 11/20

y = 11/20
