Question

Brian made a proportional copy of a figure by multiplying each side length by

Drag numbers to complete the table.

Answer 1

For side d, original length, the answer is 9

For side d, original length/copy length, the answer is 3

For side e, copy length, the answer if 7

For side f, copy length, the answer is 8

Explanation:

For side d, because there's a limited number of options, you need to find what could be divided evenly and still produce an answer that could be an option. The copy length is 3 and the only options that could be divided evenly is 9, 6, and 3. Dividing these you get

• 9/3=3

• 6/3=2

• 3/3=1

Since there isn't an option for 2 and 1, it has to be 9 for the original length and 9/3=3, 3 being the other choice.

For the last 2, you need to find what numbers makes 21 and 24 divide into 3 which is:

• 21/7=3
• 24/8=3
