How many 1/8's are in 25? What multiplication equation can you use to check your answer?

• There are 200 1/8's in 25. The multiplication equation is 200 × 1/8 = 25.

• There are 25 1/8's in 25. The multiplication equation is 25 × 1/8 = 25.

• There are 8 1/8's in 25. The multiplication equation is 8 × 1/8 = 25.

• There are 3 1/8's in 25. The multiplication equation is 3 × 1/8 = 25.

Kel has a rug with an area of 18 square feet that is 6 feet long and 3 feet wide. Kel will put the rug on a floor that is covered in 1/3-square-foot tiles. How many tiles will the rug cover? What equation can you use to check your answer?

• Number of tiles = 18 ÷ (1/3) = 18 × 3 = 54 tiles. Equation: 18 ÷ (1/3) = 54.

• Number of tiles = 18 × (1/3) = 6 tiles. Equation: 18 × (1/3) = 6.

• Number of tiles = 18 + (1/3) = 18.33 tiles. Equation: 18 + (1/3) = 18.33.

• Number of tiles = 18 - (1/3) = 17.67 tiles. Equation: 18 - (1/3) = 17.67.
