Can You Add 1/2+1/4+1/8+1/16?

Question

what does it equal?

a)12/16
b)13/16
c)14/16
d)15/16

Answer 1

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

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

15/16

- - - - - - - - - -s-

Answer 2

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

= (8+4+2+1)/16 = 15/16 (d)

Answer 3

The answer is 15/16. This because 1/2 = 8/16, 1/4 = 4/16, 1/8 = 2/16 and obviously 1/16 = 1/16, to add the fractions you need the same number on the bottom of the fractions, then simply add all the top numbers and you get 15/16!

Answer 4

d) 15/16

1/2 + 1/4 + 1/8 + 1/16 = 8/16 + 4/16 + 2/16 + 1/16
= (8 + 4 + 2 + 1)/16 = 15/16

Answer 5

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

= 8/16 + 4/16 + 2/16 + 1/16 (get the lowest common denominator)

= 15/16 (add the numerators)

Answer 6

d) = 15716

1/2 = 8/16

1/4 = 4/16

1/8 = 2/16

1/2 + 1/4 + 1/8 +12/16 = (8 +4 +2 +1)/16 = 15/16

Answer 7

We need a common denominator and in thie case this is 16.

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

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

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

= 15/16

Answer is d

Answer 8

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

get first the greatest common factor, which is 16, then distribute it to each of the fractions by dividing. *All denominators will now be 16.
numerators:
1/2 will become 8/16 --> (16/2)*1
1/4 will become 4/16 --> (16/4)*1
1/8 will become 2/16 --> (16/8)*1
1/16 will still be 1/16 --> (16/16)*1
then you add them up.(only add up the numerators, the denominator will remain the same):
8/16+4/16+2/16+1/16 =15/16

the answer is letter d)15/16

did this help? :)

Answer 9

lcd(2, 4, 8 and 16) = 16
(8 + 4 + 2 + 1)/16 = 15/16
Answer d).

Answer 10

1/2= 8/16
1/4= 4/16
1/8= 2/16
1/16= 1/16
1+2+4+8= 15
d) 15/16
