Can a common denominator of mixed numbers be 20?
gladu [14]
Yes, a common denominator is just the smallest multiple of all numbers in a group. 

So the common denominator of 4, 8 and 12 would be 4, because 4 goes into all those numbers.

Ava is in charge of bringing bottled water to a party that has 42 guests.
olya-2409 [2.1K]

Answer:

a - about 3 packs cause you have to round up

b - $50.76

Step-by-step explanation:

First you divide 42 and 18.

42/18=2.33

You have to round up cause you can't have half of a pack, you can't just buy half of a pack.

So, it is rounded to 3 packs.

Next you have to multiply the number of packs and the cost of each pack of water bottles.

16.92*3=$50.76

a - you have to buy 3 packs

b - the total cost is $50.76
