Question

1/2+1/4 =
1/2+3/4=
2/3+1=
2/5+3/5=
1 - 3/4
​

Answer 1

Explicación paso a paso:

1/2+1/4 =

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

1/2+3/4=

$\frac{1}{2} + \frac{3}{4} = \frac{2 + 3}{4} = \frac{5}{4}$

2/3+1=

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

2/5+3/5=

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

1 - 3/4

$1 - \frac{3}{4} = \frac{4 - 3}{4} = \frac{1}{4}$
