Question

calcule as diferenças , simplificando o resultado quando possivel

12/5-2/5 10/12-2/12 3/4-1/4

Answer 1

Resposta:
12/5 - 2/5 = 2
10/12 - 2/12 = 2/3
3/4 - 1/4 = 1/2

Answer 2

$a) \frac{12}{5} - \frac{2}{5} = \frac{12-2}{5} = \frac{10}{5} = 2$

$b) \frac{10}{12} - \frac{2}{12} = = \frac{10-2}{12} = \frac{(8)^{:4} \\ }{(12) ^{:4} } = \frac{2}{3}$

$c) \frac{3}{4} - \frac{1}{4} = \frac{3-1}{4} = \frac{2 ^{:2} }{4 ^{:2} } = \frac{1}{2}$
