Question

Andrea invites 12 cousins 6 aunts 4 brothers 2 sisters what fraction of her party guests are cousins?

Answer 1

To determine the fraction of cousins, you have to divide the number of cousins she invited by the total number of guests.

She invited 12 cousins, 6 aunts, 4 brothers, and 2 sisters, a total of 24 guests.

Then:

`\frac{nº\text{cousins}}{\text{total guests}}=(12)/(24)`

Both, 12 and 24 are divisible by 12, to simplify the fraction, divide the numerator and denominator by 12

`(12/12)/(24/12)=(1)/(2)`

The fraction
