Question

Sarah colored 1/2 of some birthday cards, and Rana colored 3/8 of them. If there are 32 cards in all, how many are left to be colored?

Answer 1

Answer: 4 cards are left to be colored.

Explanation:

As per given,

Fraction of total cards colored =
`\frac12+\frac38`

`=(4+3)/(8)\\\\=(7)/(8)`

Fraction of cards left to be colored =
`1-\frac78=\frac18`

Total cards = 32

Number of cards to be colored =
`\frac18*32=4`

Hence, 4 cards are left to be colored.
