Division and Subtraction Concepts

The video tutorial covers building subtraction equations from division equations using tape diagrams. It provides examples of converting division equations into subtraction problems, demonstrating the process with 18 divided by X, 35 divided by Y, and 42 divided by Z. An alternative method is introduced, using the divisor to indicate the number of units. The tutorial concludes with additional exercises for practice.

What is the first step in converting a division equation into a subtraction equation using a tape diagram?

• Write the subtraction equation

• Solve the division equation

• Draw a tape diagram

• Identify the variable

In the example 18 divided by x equals 3, what is the value of x?

• 12

• 9

• 6

• 3

How many groups are formed when 35 is divided by 5 in the tape diagram?

• 6

• 8

• 5

• 7

What is the subtraction equation for 35 divided by y equals 5?

• 35 minus 5 equals 0

• 35 minus 7 equals 0

• 35 minus 5 minus 5 minus 5 minus 5 minus 5 equals 0

• 35 minus 7 minus 7 minus 7 minus 7 minus 7 equals 0
