Subtracting Mixed Numbers

The video tutorial explains how Maya uses 5 1/4 feet of string to hang a bird feeder requiring 3 2/3 feet. It demonstrates subtracting mixed numbers by finding a common denominator and regrouping. The process involves visualizing mixed numbers, rewriting fractions, and performing subtraction to find that Maya has 1 7/12 feet of string left. The lesson focuses on understanding mixed numbers, common denominators, and regrouping in subtraction.

What is the first step in solving Maya's problem with the string?

• Cut the string into equal parts.

• Use visual models to represent mixed numbers.

• Determine the length of string needed for the bird feeder.

• Find the total length of the string.

Why do we need a common denominator when working with fractions?

• To convert them into whole numbers.

• To simplify the fractions.

• To ensure the parts are equally sized.

• To make the fractions larger.

What is the common denominator used for the fractions 1/4 and 2/3?

• 6

• 8

• 12

• 10

What is the result of regrouping 5 and 3/12?

• 5 and 8/12

• 5 and 15/12

• 4 and 3/12

• 4 and 15/12

After completing the subtraction, how much string does Maya have left?

• 1 and 5/12 feet

• 1 and 7/12 feet

• 2 and 5/12 feet

• 2 and 7/12 feet
