Answer:
20 weeks
Step-by-step explanation:
you take the total quantity of paper (4 cases times 8 reams per case = 32 reams.
If they use 3 reams every 2 weeks, it will take 22 weeks to use 33 reams
round it to the nearest ten would be 20 weeks!
The expensive one is the turkey
the least expensive one is the roast beef
I do know when I hange the mixed fraction to a whole number or proper fraction
So, you had done everything right so far (other than squaring the 2), but that was only half of the question.
to find the least common multiple, you need to first figure out what the prime factors have in common.

each have two twos. both have one 5, so we know our answer will look something like

now to figure out the other stuff... we have to represent the greatest amount of everything that is left, and we have 3s and 7s left over, so we need to figure out how many of each we need.
one has one 3 and one has two, so we need two threes. now our equation is

what's the only number we have to deal with? 7...
how many sevens does 60 have? 0, and 630 has 1, so we know we need one 7. our answer becomes
The GCF of the first two terms: 5h²
The GCF of the last two terms: 4
5h³ and 20h²
Both of these terms are divisible by 5. (constant)
Both of these terms also have at least 2 h's. (variable)
4h and 16
Both of these terms are divisible by 4.
Only one term has a variable, so that has to be left out.
