Explicação passo a passo:

$\mathsf{a)\:\left(\dfrac{2}{3}\right) \times \left(\dfrac{3}{2}\right) = \left(\dfrac{2\times3}{3\times2}\right) = \left(\dfrac{6}{6}\right) = 1}$

$\mathsf{b)\:\left(\dfrac{2}{3}\right) \times \left(\dfrac{3}{7}\right) = \left(\dfrac{2\times3}{3\times7}\right) = \left(\dfrac{6}{21}\right) = \left(\dfrac{2}{7}\right)}$

$\mathsf{c)\:\left(\dfrac{3}{5}\right) + \left(\dfrac{1}{10}\right) = \left(\dfrac{6 + 1}{10}\right) = \left(\dfrac{7}{10}\right)}$

$\mathsf{d)\:\left(\dfrac{1}{4}\right) + \left(\dfrac{2}{1}\right) = \left(\dfrac{1 + 8}{4}\right) = \left(\dfrac{9}{4}\right)}$

Answer 2

Explicação passo-a-passo:

a) 2/3x3/2=6/6=1

b) 2/3x3/7=6/21 :(3/3)=2/7

c) 3/5+1/10 m.m.c 10

(6+1)/10=7/10

d)1/4+2 m.m.c 4

(1+8)/4=9/4
