Question

а) 3/17*2.
б) 9/161*3
в)27/91*2
а)8/15*5
б)2/13*26
в)3/7*28

Answer 1

$\frac{3}{17} \times 2 = \frac{3 \times 2}{17} = \frac{6}{17}$

$\frac{9}{161} \times 3 = \frac{9 \times 3}{161} = \frac{27}{161}$

$\frac{27}{91} \times 2 = \frac{27 \times 2}{91} = \frac{54}{91}$

$\frac{8}{15} \times 5 = \frac{8 \times 5}{15} = \frac{8}{3} = 2 \frac{2}{3}$

$\frac{2}{13} \times 26 = \frac{2 \times 26}{13} = 4$

$\frac{3}{7} \times 28 = \frac{3 \times 28}{7} = 12$
