Converting Inches and Feet—Let's Practice! exercise

• Convert feet to inches.

  Hints

  Remember that 1 foot = 12 inches so 2 feet will be 12 x 2.

  A good tip for multiplication can be to multiply the tens first and then add the ones.

  6 x 12 = ?
  6 x 10 = 60
  6 x 2 = 12
  60 + 12 = 72
  6 x 12 = 72 inches

  Use a pencil and paper to help you. Multiply the ones column first, and carry over before multiplying tens.

  Use doubles when you can. Find the solution for 2 x 12. Then double this for the solution to 4 x 12.

  Solution

  • 2 feet = 24 inches because 2 x 12 = 24
  • 3 feet = 36 inches because 3 x 12 = 36
  • 4 feet = 48 inches because 4 x 12 = 48
  • 5 feet = 60 inches because 5 x 12 = 60

• Convert inches to feet.

  Hints

  Remember that there are 12 inches in 1 foot, so to convert inches to feet, divide by 12.

  When dividing by 2 digit numbers, like 12, start by dividing the tens first to get an idea if you should go higher or lower. Then consider the ones.

  Example:
  84 ÷ 12 = ?
  10 x 8 = 80
  8 x 2 = 16
  80 + 16 = 96, this is too high.

  Next try 7.

  7 x 10 = 70
  7 x 2 = 14
  70 + 14 = 84
  84 ÷ 12 = 7

  Solution

  • 48 inches ÷ 12 = 4 feet
  • 108 inches ÷ 12 = 9 feet
  • 72 inches ÷ 12 = 6 feet
  • 24 inches ÷ 12 = 2 feet

• Convert feet to inches.

  Hints

  Since there are 12 inches in 1 foot, you'll need to multiply the number of feet by 12.

  A good tip for multiplication can be to multiply the tens first and then add the ones.

  6 x 12 = ?
  6 x 10 = 60
  6 x 2 = 12
  60 + 12 = 72
  6 x 12 = 72 inches

  Use a pencil and paper to help you. Multiply the ones column first, and carry over before multiplying tens.

  Solution

  • 4 feet = 48 inches because 4 x 12 = 48.
  • 7 feet = 84 inches because 7 x 12 = 84.
  • 5 feet = 60 inches because 5 x 12 = 60.

• Convert inches to feet.

  Hints

  Since there are 12 inches in 1 foot, you'll need to divide the number of inches by 12.

  7 x 10 = 70
  7 x 2 = 14
  70 + 14 = 84
  84 ÷ 12 = 7

  Solution

  • 48 inches = 4 feet because 48 ÷ 12 = 4.
  • 120 inches = 10 feet because 120 ÷ 12 = 10
  • 108 inches = 9 feet because 108 ÷ 12 = 9
  • 96 inches = 8 feet because 96 ÷ 12 = 8

• Calculate how many feet there are.

  Hints

  Example:
  84 ÷ 12 = ?
  10 x 8 = 80
  8 x 2 = 16
  80 + 16 = 96, this is too high.

  Next try 7.

  7 x 10 = 70
  7 x 2 = 14
  70 + 14 = 84
  84 ÷ 12 = 7

  Solution

  • 12 inches is equal to 1 foot.
  • 24 inches is equal to 2 feet.
  • 36 inches is equal to 3 feet.

• Convert inches to feet and feet to inches.

  Hints

  There are 12 inches in a foot.

  To convert inches to feet, divide by 12.

  For example, 24 inches is equal to 2 feet because 24 ÷ 12 = 2.

  There are 12 inches in a foot.

  To convert feet to inches, multiply by 12.

  For example, 6 feet is equal to 72 inches because 6 x 12 = 72.

  Use a pencil and paper to help you.

  Solution

  • There are 5 feet in 60 inches because 60 ÷ 12 = 5.
  • There are 72 inches in 6 feet because 6 x 12 = 72.
  • There are 7 feet in 84 inches because 84 ÷ 12 = 7.
  • There are 84 inches in 7 feet because 7 x 12 = 84.
