Question

$\frac{1}{2} + \frac{3}{4}$

$\frac{ 2}{5} + \frac{3}{6} + \frac{1}{3}$

$\frac{5}{4} + \frac{3}{6}$
​

Answer 1

Explicação passo-a-passo:

1/2+3/4=(2×3+1×4)/(2×4)

1/2+3/4=(6+4)/8

1/2+3/4=10/8 (dividindo a fração por 2)

1/2+3/4=5/4

=====

2/5+3/6+1/3=(12+15+10)/30 mmc=30

2/5+3/6+1/3=(27+10)/30

2/5+3/6+1/3=37/30

=====

5/4 + 3/6=(4×3+5×6)/(4×6)

5/4+3/6=(12+30)/24

5/4+3/6=42/24(dividindo a fração por 6)

5/4+3/6=7/4
