Estimate the sum or difference of 1/5+3/7=

Sum: 22/35 Difference: -8/35

Step-by-step explanation:

Because when adding and subtracting fractions you need to get common denominators you have to multiply 1/5 by 7/7 and 3/7 by 5/5.

now that both of the fractions have common denominators they can be added and subtracted very easily. you only have to worry about the numerator and keep the same denominator.
