144/200 can be simplified to 72/100, which is equal to 0.72 or 72%
225/100 is equal to 2.25 or 225%
42/50 can be changed into 84/100 which would then be .84 or 84%
Step-by-step explanation:
If you give something a denominater of 100 then to find the decimal you just move the decimal place over 2 spots to the left, and it is just the numerator for the percent
X equals 62 because you take 147 and subtract it from 180 and that gives you 33. then you add 33 and 85 together to give you 118. Then you subtract 118 from 180 and that gives you 62. x=62
