Answer:
4x-18y-18/12
Step-by-step explanation:
x/3 - 2(y+1)/4
1. Find the Least Common Multiple for the denominators (in this case it is 12)
4x/12 - 6(3y+3)/12
2. Use PEMDAS
4x/12 - 18y+18/12
3. Distribute the arithmetic sign
4x/12 + -18y-18/12
4. Combine the fractions
25% = .25
20% = .20
9% = .09
.25+.20+.09=.59
