Answer 1

Explicație pas cu pas:

$\frac{\not7}{\not12} \times \frac{\not36}{\not56} = \frac{1}{1} \times \frac{3}{8} = \bf \frac{3}{8}$

$1 \frac{5}{6} \times \frac{9}{22} = \frac{\not11}{\not6} \times \frac{\not9}{\not22} = \frac{1}{2} \times \frac{3}{2} = \bf \frac{3}{4}$

$2 \frac{3}{4} \times \frac{16}{22} = \frac{ \not11}{ \not4} \times \frac{\not16}{\not22} = \frac{1}{1} \times \frac{4 ^{(2} }{2} = \bf 2$

$\frac{\not5}{\not18} \times \frac{\not2}{\not5} = \frac{1}{9} \times \frac{1}{1} = \bf \frac{1}{9}$

$\frac{\not3}{\not8} \times \frac{\not24}{\not27} = \frac{1}{1} \times \frac{3 ^{(3} }{9} = \bf \frac{1}{3}$

$3 \frac{1}{7} \times \frac{14}{33} = \frac{ \not22}{\not7} \times \frac{\not14}{\not33} = \frac{2}{1} \times \frac{2}{3} = \frac{4}{3} =\bf 1 \frac{1}{3}$

$\frac{6}{11} \times 4 \frac{7}{12} = \frac{ \not6}{\not11} \times \frac{\not55}{\not12} = \frac{1}{1} \times \frac{5}{2} = \frac{5}{2} = \bf 2 \frac{1}{2}$

$\frac{ \not11}{\not12} \times \frac{\not3}{\not11} = \frac{1}{4} \times \frac{1}{1} = \bf \frac{1}{4}$

$\frac{ \not4}{\not9} \times \frac{\not27}{\not36} = \frac{1}{1} \times \frac{3 ^{(3} }{9} = \bf \frac{1}{3}$

$2 \frac{2}{9} \times \frac{9}{20} = \frac{ \not20}{\not9} \times \frac{\not9}{\not20} = \frac{1}{1} \times \frac{1}{1} = \bf 1$
