Question

ACTIVIDAD 2: Resuelva las siguientes multiplicaciones de racionales

(12/5 . 7/(4 )) ÷ (-2/3)=
(9/8 .5/4)÷ (1/4-5/6)=
3/4-{2/5+ [(2/5+3/5)- (1/6+1/2)]}=

Answer 1

Explicación paso a paso:

1) (3/5*7) ÷ (3/2) = 21/5 ÷ 3/2 = 21/5*2/3 = 14/5

2) (45/32) ÷ (3/12-10/12) = (45/32)÷(-7/12)= 45/32*12/7= 15/8

3) 3/4- {(2/5+3/5)-(1/6+1/2) = 3/4- {(1)-(4/6)}= 3/4-2/6 = 9/12-4/12 = 5/12
