Arectangle has an area of 12 square feet and a length of 5 feet. what is its width?

It is certainly not 60.
A=length x width
12=5 x width
Divide both sides by 5
Width = 12/5 or 2 and 2/5

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
