A rectangular tabletop has a length of 4 3/4 feet and an area of 11 7/8 square feet. What is the width of the tabletop

First I would turn the mixed fractions into improper fractions so it will be easier division. That would make 4 3/4 become 19/4 and 11 7/8 become 95/8. Next, the formula for area is length x width = area. If you plug in the numbers, it will become 19/4x=95/8, x being the width. You would divide 95/8 by 19/4 and end up with 5/2 or 2 1/2.

A=B*H where B=base, H=height and A=area

area = 11 and 7/8

B = 4 and 3/4

let H = x

11 and 7/8=4 and 3/4 * x

x = (11 and 7/8) / (4 and 3/4)

x = 5/2

Therefore the width of the tabletop is 2.5 feet
