Question

calcule e simplifique:
ME AJUDEMMMMM!?​

Answer 1

J:

$\frac{3}{5} \times \frac{2}{7} = \frac{6}{35}$

K:

$\frac{2}{3} \times \frac{5}{4} \times \frac{1}{2} = \frac{10}{24} = \frac{5}{12}$

L:

$\frac{3}{40} \times \frac{20}{21} = \frac{60}{840} = \frac{6}{84} = \frac{1}{14}$

M:

$2 \frac{7}{5} \times \frac{11}{6} \\ \\ \frac{17}{5} \times \frac{11}{6} = \frac{187}{30}$

N:

$\frac{2}{3} \div \frac{5}{2} \\ \\ \frac{2}{3} \times \frac{2}{5} = \frac{4}{15}$

O:

$\frac{3}{4} \div \frac{7}{1} \\ \\ \frac{3}{4} \times \frac{1}{7} = \frac{3}{28}$

P:

$7 \frac{1}{3} \div \frac{6}{1} \\ \frac{22}{3} \times \frac{1}{6} = \frac{22}{18} = \frac{11}{9}$

Q:

$( \frac{2}{4} )^{0} = 1$

R:

$(\frac{1}{2})^{2} \\ \\ \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}$

S:

$(\frac{1}{3})^{4} = \frac{1}{81}$

T:

$(\frac{3}{2})^{2} = \frac{9}{4}$
