SOME TERMINOLOGY FOR FRACTION PROBLEMS

In solving mathematics problems, it can be very useful to find some other

(solved) problem which is “the same” as the one we are looking at One way to

see how fraction problems are the same as or different from each other is to

notice that in each of the problems there are three possible components:

There is the whole, which is given as some amount of stuff—like

lemonade or acreage, or distance. If you solve the problem by diagram, it will be

what you first draw. In the examples above, it would be Mrs. Jones's sugar

supply, or the camp lawn, or the distance from home to school.

There is a part of a whole, which is the smaller piece that each problem

has. This is the sugar for one batch of cookies, or the distance to Joe's house,

or the part of the lawn that Dawn has mowed.

There is a portion, which is the ratio between the part of the whole and

the whole. For instance, we are told that each batch of cookies used 1/4 of the

available sugar (that is the portion of the sugar used to make a batch), and that

Dawn has mowed 3/4 of what she needs to (that is, the portion of her job).

One of the things that makes these problems tricky is that any of the

quantities—the whole, the part or the portion—can be expressed as a fraction, so

that you cannot tell which is the portion by looking for the fraction. However, you

might notice that in general the whole and the part have units attached, like

quarts or miles (or at least could have—for instance, the lawn could just as well

be 1 acre of lawn.) The portion, on the other hand, doesn't. This is because the

portion is a relationship between the part and the whole and is not an actual

quantity.

II FRACTION PROBLEMS TO BE SOLVED BY DIAGRAM

Directions: Solve the problems below by diagram USING THE GROUND

RULES ABOVE. Look over the example solutions above, but remember there

are many ways to solve any particular problem by diagram. Be creative—don't

just follow.

1) Ms. Jones had 6 pints of lemonade. She gave 1/4 of it to her class. How many

pints did she keep?

2) Ms. Alvarez has 2 1/2 bars of candy. She wants to divide it evenly among her

4 tap-dance students. How many candy bars does each student get?

3) Nan's go-cart requires 2/3 of a gallon of gas to fill it up. She has 2 2/3

gallons. How many times can she fill it up?

4) In the January White Sale, Grant bought towels for which he paid $48. All

prices in the sale were "1/3 off the regular price." What would he have paid for

the towels at the regular price?

5) Pietro has 3/4 of a quart of milk. He uses 2/3 of it for a milk shake. What part

of a quart of milk did he use?

6) Miguel picked 3 3/4 quarts of blueberries. He gave his friend Sally 3 quarts of

blueberries. What portion of the blueberries he picked does he have left?

7) Ming ran 1/4 of a kilometer and then walked 5/6 of a kilometer. What was the

total distance she covered?

8) Jose has 2 1/3 yards of material. He uses 1 1/2 yards to make a vest. How

much does he have left?

9) At a pizza party Frank ate 1/3 of each of four pizzas. Sarah ate 1/2 of each of

three different pizzas. Who ate more?

10) Pablo has 1 1/3 gallons of paint. If he uses 1/4 of what he has, how much

paint has he usedportion

of his run does he have left?
