Question

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

(4/3) (3) =

(3/5) (4/6) (2/3) =


AYUDAAAA!!!​

Answer 1

Explicación paso a paso:

$\frac{5}{4} + \frac{2}{5} - \frac{1}{2} \\ mcm(4 - 5 - 2) = 20 \\ \frac{25 + 8 - 10}{20} \\ \frac{23}{20}$

$( \frac{4}{3} )(3) \\ \frac{4 \times 3}{3} \\ 4$

$( \frac{3}{5} )( \frac{4}{6} )( \frac{2}{3} ) \\ \frac{3 \times 4 \times 2}{5 \times 6 \times 3} \\ \frac{2}{5 \times 3} \\ \frac{2}{15}$
