Question

Compare the lengths of the segments. Rope C is _______ times as long as rope A. Write a multiplication equation

Answer 1

Twice ; c = 2a ; a = c/2

Explanation:

Since the drawing area has been gridded, accurate calculation could easily be performed ;

Rope A occupies 5 boxes

Rope C occupies 10 boxes

Hence,

10 boxes for C / 5 boxes for A

Therefore,

Rope C is Twice the length of Rope A.

If length of Rope A = a ; length of Rope C = c

Then, a multiplication equation for the length of Rope C equals ; c = 2a

Division equation :

a = c/ 2
