Answer:
3/2 is greater than 1
Step-by-step explanation:
A little trick to immediately know if a number is more or less than when it involves fractions versus whole numbers is that improper fractions will always be greater than 1.
If you want to confirm this, dividing 3/2 equals 1.5, ergo 1.5 > 1.
In essence, improper fractions will always represent a number greater than one contrasted to proper fractions because if you put it on a perspective (let's say you have 13 pie slices but you only needed 12, that means there is a pie slice that's extra that makes it greater than the original pie slices).
Hope that helps :)

Answer:
13.9%
Step-by-step explanation:
Given data
Expected weight = 230 pounds
Actual weight= 262 pounds
Required
The percent error
Error= Actaul- expected/ expected *100
Error= 262-230/230*100
Error=32/230*100
Error=0.139*100
Error=13.9%
Hence the error is 13.9%
