Answer 1

Răspuns:

$d) \: 2 \frac{3}{4} \times 1 \frac{5}{22} = \frac{ \not11}{4} \times \frac{5}{ \not22} = \frac{1}{4} \times \frac{5}{2} = \red{ \frac{5}{8} }$

$e) \: 9 \frac{2}{14} \times \frac{42}{128} \times 11 \frac{1}{ \not3} \times \frac{ \not6}{68} = \frac{ \not128}{ \not14} \times \frac{ \not42}{ \not128} \times 11 \frac{1}{1} \times \frac{2}{68} {}^{(2} = 3 \times 11 \times \frac{1}{34} = 33 \times \frac{1}{34} = \red{ \frac{33}{34}}$

$f) \: \frac{ \not3}{5} \times \frac{2}{ \not7} \times \frac{ \not21}{ \not18} = \frac{1}{5} \times 2 \times \frac{3}{6} {}^{(2} = \frac{ \not2}{5} \times 2 \frac{1}{ \not2} = \red{ \frac{1}{5} }$
