Question

Quanto que dá a soma das fracoes 1/2+1/4+1/8+1/16+1/16

Answer 1

mmc (2,4,8,16) = 16
1/2 = 16:2 / 16 = 8/16
1/4 = 16:4 / 16 = 4/16
1/8 = 16:8 / 16 = 2/16

8/16 + 4/16 + 2/16 + 1/16 + 1/16 = 
(8+4+2+1+1)/16 = 16/16 = 1

Answer 2

1/2 + 1/4 +1/8 + 1/16+ 1/16

mmc 

2-4-8-16]2
1-2-4- 8 ]2
1-1-2- 4 ]2
1- 1-1- 2]2
1-  1- 1-1

2* 2 * 2 * 2= 16

8/16 + 4/16+2/16 + 1/16+1/16 = 16/16 = 1
