Question

Shiva read 1/2 of a book in the morning, and she read some more at night. By the end of the day, she still had 1/3 of the book left to read. How much of the book did Shiva read at night?

Answer 1

Shiva had read 1/6 of the book that night.

1/2 + n = whole book - 1/3

1/2 + n = 1 - 1/3 = 3/3 - 1/3

1/2 + n = 2/3

The Lowest Common denominator of 2 and 3 is 6. Change each fraction to 6ths.

1/2 = 3/6. and 2/3 = 4/6

So 3/6 + n = 4/6

Subtract 3/6 from each side

3/6 + n - 3/6. = 4/6 - 3/6

n. = 1/6

Shiva had read 1/6 of the book that night.
