# Ratio calculator

# Solution:

### y = -101/5 = -20.2

## -8/5 = ((-20.2)+1)/12

Solve ratios or proportions a:b=c:d for the missing value. Missing value mark as variable x (or other a-z). We also accept decimals and some basic mathematical operations. Ratios enter in the form such as:

1/x = 3/8

180 = 1:2 divide a number in the ratio

2:x = 4:5

x/2 = 3:5

2.2/x = 5.5/6.6

5/6 = x:12

-8/5 = 12/y

-8/5 = (y+1)/12
