Question

-6/5 – 2(9/2+5/15) – (3/20 – 3/30)

Answer 1

Respuesta:

655/60

Explicación paso a paso:

-6/5 – 2(9/2+5/15) – (3/20 – 3/30)

-6/5 – 2{[15(9)+2(5)/30]} – (3/20 – 1/10)

-6/5 – 2[(135+10)/30] – (3-2)/20

-6/5 – 2(145/30) – 1/20

-6/5 – 145/15 – 1/20

[12(-6)-4(145)-3(1)]/60

(-72-580-3)/60

655/60

5-15-20|3

5- 5-20|4

5-  5-  5|5

1-  1-  1

MCM(5,15,20)=3*4*5

MCM(5,15,20)=60
