Answer:
5 1/10 c or 3 1/10 +2
When you simplify the expression, you combine like terms. 5 7/10 c and -2 3/5 c are like terms. You multiply two on the numerator and denominator to make it 6/10. You subtract 2 6/10c from 5 7/10c to make it 3 1/10. This next step is easy. 8 and -6 are like terms. So you subtract 6 from 8 to get two. The final step is optional. 3 1/10 + 2= 5 1/10
