Question

ayudenme:
1) ( 9/3 - 1/4 - 1/8 - 1/16) x 8

2) ( 1/3 - 1/5 ) x ( 1/60 + 10/25 ) x 5 4/15

Answer 1

1)  mcm = 48

(((9*16)+(1*12)+(1*6)+(1*3))/48)*8
(144+12+6+3)/48*8

(165/6)=55/2

2)  mcm  =  15, 300

(((1*5)-(1*3))/15)*(((1*5)+(10*12))/300)*79/15
((5-3)/15)*((5+120)/300)*79/15
(2/15)*(5/12)*(79/15)

79/270
