Solve a Real World Problem Dividing a Whole Number by a Fraction

The video tutorial addresses a standardized math test question involving dividing a whole number by a fraction. It consists of two parts: Part A focuses on setting up an equation to determine the number of 1/4 cup servings from 3 cups of raisins, while Part B involves dividing a 1/4 cup serving into two smaller servings. The tutorial uses visual aids and explains the mathematical operations, including the use of reciprocals, to solve the problems. The video concludes with encouragement to continue learning math.

What is the main mathematical operation used to solve the problem of dividing 3 cups of raisins into 1/4 cup servings?

• Addition

• Division

• Subtraction

• Multiplication

Which equation represents the number of 1/4 cup servings Mr. Shapiro can make from 3 cups of raisins?

• Multiply by the reciprocal

• Subtract the servings

• Divide by the whole number

What is the reciprocal of 2, which is used in the calculation for part B?

• 2

• 4

• 1/2

• 1/4

What is the size of each smaller serving when a 1/4 cup is divided into two equal parts?

• 1/8 cup
