Elena studied her diagrams and noticed that she always took the same two steps to represent division by a fraction on a tape diagram. She said:
“My first step was to partition each 1 whole into as many parts as the number in the denominator. So if the expression is 6÷3/4, I would partition each 1 whole into 4 parts. Now I have 4 times as many parts.
My second step was to put a certain number of those parts into one group, and that number is the numerator of the divisor. So if the fraction is 3/4, I would put 3 of the 1/4s into one group. I could then tell how many 3/4s are in 6.”
Which expression represents how many 3/4s Elena would have after these two steps? Be prepared to explain your reasoning.
