If an ice cream container has 4 servings and each serving is equal to 2 ounces, the total number of ounces in the container can be found by multiplying 2 by 4.

This results in 8 ounces. 

We know that one-third of the pie is 2 slices. We can set up an equation:

In other words, one-third times the total slices in the pie will be equal to 2 slices.

Multiply both sides of the equation by 3.

The fraction on the left side cancels.

There are a total of 6 slices in the pie.

If the class eats  of the cookies and  remain, this means that . Therefore,  of the batch will be equal to  cookies, as  is twice the value of , and  is twice the value of . 

The entire batch of cookies will be equal to .

Thus,  is the correct answer. 

The first step is to convert the coins into their values in cents. 

If we look at the combination of  quarter,  dimes,  nickels, and  pennies, the following expression can be used to determine the coins' value in cents:

Therefore, the correct answer is  quarter,  dimes,  nickels, and  pennies.

As for the incorrect answers,  quarter,  dimes,  nickels, and  penny adds up to  cents;  quarters,  dimes,  nickels, and  pennies adds up to  cents; and  quarter,  dimes,  nickels, and  pennies adds up to  cents.

If the sales tax is , then this means that for every purchase of , an  tax will be charged. 

Given that the shoes are  (half of ), half the sales tax of  should be charged, which is a value of . 

Since , the shoes will cost  after sales tax. 

If Anita bought a pair of boots for  that was on sale for  off, this means she would get  off. But if she was taxed at  on the full price, this would be equal to . 

Therefore, the total she would have to pay would be equal to , because .

If Arnold made  tutoring, that means that he gave  tutoring sessions because  divided by  (his rate per tutoring session) is equal to . 

Given that Arnold must spend half an hour preparing for each session, the total number of hours it took him to earn  is equal to:

If Joe has one third of his assignment to complete after finishing  problems, that means that  is equal to two-thirds of the entire set. Knowing this, we can write out the equation  and solve for  in order to find how many problems make up Joe's homework assignment.

We can solve this equation by cross-multiplying to get , which simplifies to .

To find , we can divide each side of the equation by . This gives us , so there are  problems in Joe's homework assignment.

Given that there are 3 birds in the tree who are then joined by their mates, there are 6 total birds in the tree. If two-thirds of the birds fly away, 4 birds leave, and 2 birds are left in the nest

To find out how many students are in the class, we first need to find the number of girls in the class. For every  boys, there will be  girl. There are  groups of  in a group of  (or, put another way, ), so the class has  groups of  boys. That means we also have  groups of  girl.  is , so altogether we have  boys and  girls. , so the correct answer is .
