Sam walked 3/5 of a mile to school. He also walked 6/7 of a mile on his way home. How far did Sam walk in all?

(3)/(5) + (6)/(7) you have to get the common denominator which will be:


(3*7)/(5*7) + (6*5)/(7*5) = (21)/(35) + (30)/(35) = (51)/(35) or 1 (16)/(35) or 1.46

Hope that helps

3/5 of 1 mile = 3/5 × 1 = 3 / 5 = 0.6 mile
6/7 of 1 mile = 6/7 × 1 = 6 / 7 = 0.85 mile

total walking distance = 0.6 + 0.85 = 1.45 miles

IF IN FRACTIONS : 3/5 + 6/7
to equalise the denominators multiply 3/5 by 7...........and in 2nd fraction multiply 6/7 by 5

this will become : 21/35 + 30/35
= 51/35 miles

HOPE IT HELPED !!
