Question

A set of 6 number cards contain the numbers 2, 5, 7, 8, 9, and 11. Which ratio is less than the ratio of odd number cards to total cards in this set?

Answer 1

`Ratio = 2:3`

Explanation:

Given

`Cards = \{2,5,7,8,9,11\}`

Required

Ratio of odd numbers to total

First, list out the odd numbers

`Odd = \{5,7,9,11\}`

The card has 4 odd numbers out of a total of 6.

So, the ratio is:

`Ratio = Odd : Total`

`Ratio = 4:6`

Divide by 2

`Ratio = 2:3`

Hence, the ratio of odd to total is 2 to 3
