Question

calcule a fração:
a) 1/5+3/2
b)4/3+3/2
c) 6/4-1/2

Answer 1

OI

a) $\frac{1}{5} + \frac{3}{2}$

o mmc de (5,2)=10

$\frac{2 + 15}{10}$

$\frac{17}{10}$

b) $\frac{4}{3} + \frac{3}{2}$

o mmc de (3,2) = 6

$\frac{8 + 9}{6}$

$\frac{17}{6}$

c) $\frac{6}{4} - \frac{1}{2}$

o mmc de (4,2) = 4

$\frac{6 - 2}{4}$

$\frac{4}{4} : 4$

$1$
