### Example Question #1 : Whole And Part

On Friday night, Maria sells  of her stock of apples.  On Saturday, she sells  of the remaining apples.  What fraction of her original stock of apples does Maria have left for sale on Sunday?

### Example Question #421 : Arithmetic

Michael Phelps’ workout program consists of Aerobics, Bench Presses, and Cycling.  Aerobics and Bench Presses take a total of 24 minutes, Bench Press and Cycling take a total of 40 minutes, and the entire workout takes a total of 56 minutes.  How many minutes are required for the Bench Press portion of his workout?

8 minutes

4 minutes

16 minutes

40 minutes

32 minutes

8 minutes

Explanation:

To find your answer, we would use substitution within a system of equations.  If (A+B) +C = 56, we can replace (A+B )= 24 to get (24) + C = 56, Thus making C = 32.  Then we can replace C with 32 in the equation      B+C = 40, thus making B + (32) = 40 to get an answer of 8.

### Example Question #1 : How To Find The Whole From The Part With Fractions

A wedding planner knows she must deliver 85 small fruits and 40 large fruits to the wedding event. She knows that one basket can hold either 5 small fruits or 3 large fruits. What is the minimum number of baskets she must bring to the event to fulfill their demand?

Explanation:

To know the minumum number of baskets required for each size, simply divide the number of fruits required by the basket capacity for each fruit:

(we must round up to nearest whole number for practical purposes)

Since we need to bring both the large and small fruits to the event, we need to add these two values:  baskets total.

### Example Question #1 : How To Find The Whole From The Part With Fractions

After saving her money for six weeks, Felicia has saved up . If she saves three-fifths of her pay each week, how much does she make in a week?

Cannot be determined from the information provided

Explanation:

When working with fractions or percents, it is often really helpful to write out an equation showing what you need to find. In this case, we know that three-fifths of Felicia's weekly pay (our variable—let's call it ) over six weeks results in , so our equation looks like this:

So, we want to simplify and rearrange this equation. Start by multiplying the  with the :

Then, multiply both sides by , the reciprocal of :

So, , and we now know Felicia's weekly pay!
