Line Plot Fractions with Different Denominators

Ryan was creating equivalent fractions for 12/16. He says 12/16 = 3/4. Explain how Ryan found the equivalent fraction.

• Ryan multiplied the numerator by 4 and multiplied the denominator by 12.

• Ryan multiplied the numerator by 4 and multiplied the denominator by 4.

• Ryan divided the numerator by 4 and multiplied the denominator by 3.

• Ryan divided the numerator by 4 and divided the denominator by 4.

Answer explanation

Remember, whatever you multiply or divide on top, you must do the same on the bottom.

Ryan started with 12/16 and then went to 3/4. Since he started with larger numbers and went to smaller numbers, that tells us he divided.

12 divided by 4 gives us 3.

16 divided by 4 gives us 4.

He is correct since he divided 12/16 by 4 both top and bottom with the correct quotients.
