Unit Area

Use the pattern from the previous problem to explain how many squares with side length 1/8 inch would fit in 1 square inch.

• The denominator is 8. So 8 + 8 = 16, so 16 squares with side length 1/8 inch would fit into 1 square inch.

• The denominator is 8. So 8 x 8 = 64, so 64 squares with side length 1/8 inch would fit into 1 square inch.

• The numerator is 1 and the denominator is 8. So 1 x 8 = 8, so 8 squares with side length 1/8 inch would fit into 1 square inch.
