 4/5 + 5/8
=32+25/40
=57/40
=1 17/40
LE ME EXPLAIN
4/5 + 5/8
1. Multiply numerators and denominators of different fraction. Add them to get the numerator. N1 = 4, N2 = 5, D1 = 5, D2 = 8. Multiply N1 by D2, N2 by D1. Add it to get the numerator: N1D2 = 32, N2D1 = 25. 32+25=57=Numerator.
2. Multiply the denominators. That will be your denominator...
D1 = 5, D2 = 8. 5x8=40=Denominator.
3. If possible, change it to Mixed Fraction: 57/40 = 1 17/40
