Answer 1

`@Neo`

`13,25:0,125+13,25:0,25-13,25:0,5`

`=13,25:1/8+13,25:1/4-13,25:1/2`

`=13,25xx8+13,25xx4-13,25xx2`

`=13,25xx(8+4-2)`

`=13,25xx10`

`=132,5`

Answer 2

13,25:0,125+13,25:0,25-13,25:0,5

\(=13,25:\dfrac{1}{8}+13.25:\dfrac{1}{4}-13,25:\dfrac{1}{2}\)

\(\text{ = 13,25 x 8 + 13,25 x 4 - 13,25 x 2}\)

\(\text{= 13,25 x ( 8 + 4 - 2)}\)

\(=13,25\times10\)

\(\text{= 132,5}\)
