The teacher has 12 green and 15 purple stickers the students are given `an equal number of each color stickers how many green and purple stickers does each students get

Each student gets 4 green stickers and 5 purple stickers or a total of 9 stickers.

Explanation:

The greatest common divisor (GCD) of two or more natural numbers or integers (not numbers with decimals) is the largest number that divides them. In other words, the Greatest Common Divisor is the greatest of the common divisors of several numbers. To calculate it, each of them is decomposed into prime factors. The GCD is the result of multiplying the factors that are repeated in all the decompositions, affected by the smallest exponent.

In the event that no factor is repeated, the GCD of those numbers is 1, and the numbers are said to be "prime to each other."

In this case, the decomposition of 12 and 15 is:

12 = 2²*3.

15=3*5

So the GCD between 12 and 15 is 3

Now, to calculate how many green and purple stickers each student receives, you simply divide the amount of each sticker color by 3.

12÷3= 4

15÷3= 5

So, each student gets 4 green stickers and 5 purple stickers or a total of 9 stickers.

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
