Marisol is painting on a piece of canvas that has an area of 180 square inches. The length of the Painting is 1 1/4 times the width. What are the dimensions of the painting

Answers

let x be a width
1 1/4x be the length (or it can be 5/4 i prefer this one)

formula for rectangle
lxw=a
5x/4(x)=180
4[5x^2/4=180]4
5x^2=720
x^2=144
x=12

so width is 12 and length is
5x/4
5(12)/4
60/4
=15

Equivalent mixed number for: 21/8 = ?

Answers

21/8 would be the same as 2 5/8
You can divide 8 from 21 twice, which sums up to 16.
21 - 16 = 5
The two 8's that have been taken away are now equivalent to 1, because 8/8 = 1
1 + 1 = 2
Therefore, the answer is 2 5/8

2 5/8 hope this helps
