13.Calcula y simplifica:
7/5 + 1/3 =        3 + 1/5=         5  -4/3=      5/6- 3/4 =

Answer 1

3/5:4 =  3/5*1/4=3/20.

1/2:5 =  1/2*1/5=1/10.

1/12x3 = 3*1/12=3/12=1/4

6x5/12 = 30/12=5/2

7/5+1/3 =  7*3/3*5+5*1/3*15=21/15+5/15=26/15.

3+1/5=   5*3/5+1/5=15/5+1/5=16/5.

5-4/3=   5*3/3-4/3=15/3-4/3=11/3.

5/6- 3/4 = 5*2/12-3*3/12=10/12-9/12=1/12
