How many squares with side length 1/4 inch will fit into 1 square inch?
What pattern do you notice about the relationship between the side length of the smaller squares and the number of squares that will fit in 1 square inch?
It is a random guess.
Multiply both the numerator by the denominator to find the number of small squares that fit in the large square.
Multiply the fraction denominator by itself gives the number of small squares that fit in the large square.
Adding the fraction denominator to itself gives the number of small squares that fit in the large square.
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.
