Question

Efetue as operações indicadas:
1/3+1/5=
1/2+1/7=
3/5+1/2=
3/4-1/2=
4/8-1/2=
3/9-8/3=

Answer 1

Explicação passo-a-passo:

1/3 + 1/5 = 5/15 + 3/15 = 8/15

1/2 + 1/7 = 7/14 + 2/14 = 9/14

3/5 + 1/2 = 6/10 + 5/10 = 11/10

3/4 – 1/2 = 3/4 – 2/4 = 1/4

4/8 – 1/2 = 4/8 – 4/8 = 0

3/9 – 8/3 = 3/9 – 24/9 = –21/9 = –7/3
