Knitting a scarf

Rebecca is knitting a scarf. She runs out of yarn when the scarf is 1 1/2 feet long, which is ⅔ of the length she wants to make. How long is the scarf when finished? Write a multiplication and division equation to represent this situation.

Correct answer:

x =  2 14 = 9/4 ft

Step-by-step explanation:

a=121=1+21=21 2+1=22+1=23=1.5 ft  a=32 x 1.5=32 x  1.5=2/3 x  2x=4.5  x=24.5=2.25  x=49=2.25=49 ft=241 ft=2.25 ft
