Question

The length of a rectangle is 4/5 feet. The width is 5/8 feet. How much greater is the length of the rectangle than the width?

a.1/5 ft
b.7/40 ft
c.3/20 ft
d.1/3 ft

Answer 1

21.9%

Answer 2

You need to compute length - width, or
\[\frac{4}{5}-\frac{5}{8}\]Start by putting the fractions over a common denominator. You can multiply the first fraction by \(\frac{8}8\) and the second fraction by \(\frac{5}5\). Both fractions are equal to 1, so don't change the value of the fractions you multiply them with, but will give you a common denominator after you have done so.

Answer 3

@dwelsher sorry, that isn't correct... if you wanted to find the percentage that the length is greater than the width, the correct computation is \[\frac{\text{length}-\text{width}}{\text{width}}*100\%\]

Answer 4

you must have divided by length instead of width.

Answer 5

lets see if I understand. we want to find how much greater the length is than the width.
then first we have to subtract the width from the length to calculate the difference of .8-.625=.175. Is this right? How much greater is .175 of .625?=~27% not21.9 must be a simple question to determine the difference? which would be b?7/40=.175 As you can see I didn't divide by anything. If not please get back to me!

Answer 6

.175/.625 = 0.28 In determining "how much greater is .175 of .625" you're doing that division, whether you realize it or not.

Answer 7
