24 guests were invited to a party. 1/3 brought drinks. 1/4 brought drinks. The rest brought utilery. How many brought utilery?

Answer: 10 guests brought utilery

Step-by-step explanation:

If we take 24 out of the problem right now and replace it with x, you can find the the fraction of people that brought utilery.

So x=24 just so you remember

x-1/3x-1/4x = #of guests who brought utilery.

x-7/12x = 5/12x

Now if we plug in x=24 into our equation,

5/12 (24) = 10 guests
