If i raked 5/12 of grass and someone else raked 4/9 how much more needs to be raked

To solve this problem, you can subtract the sum of 5/12 and 4/9 from 1. To find the sum of 5/12 and 4/9, you need to make them have common denominators.
5/12*3/3=15/36
4/9*4/4=16/36

Now add the two fractions.
15/36+16/36=31/36

Lastly, subtract the sum from 1.
1-31/36=5/36.

Idk what the answers are but you gotta multiply the parenthesis by the 4 and subtract the 40 from 34 if I’m wrong use this app called Photomath
