A printer has 15 rolls of newsprint in a warehouse. What fractional total will remain (in lowest terms) after 10 rolls are used?

What is a fraction?

part/whole = fraction

10/15 = fraction

5 into 10 = 2 (our numerator)

5 into 15 = 3 (our denominator)

Final answer: 2/3

Done!

To find the fractional total that will remain, we need to calculate the difference between the initial number of rolls and the number of rolls used.

The initial number of rolls is 15, and 10 rolls are used, so the remaining rolls can be calculated as:

Remaining rolls = Initial rolls - Rolls used
Remaining rolls = 15 - 10
Remaining rolls = 5

Therefore, there will be 5 rolls remaining.

To express this as a fractional total in the lowest terms, we need to write the fraction using the remaining rolls as the numerator and the initial rolls as the denominator.

Fractional total = Remaining rolls / Initial rolls
Fractional total = 5 / 15

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 5 in this case:

Dividing the numerator by 5: 5 ÷ 5 = 1
Dividing the denominator by 5: 15 ÷ 5 = 3

So, the fractional total that will remain in lowest terms is 1/3.

Yay! You're right! :-)

thank you

If you show us how you think the problem should be solved, we'll be glad to check your work and your answer.

would it be 10/15

You're right as far as you went. :-) Now reduce 10/15 to its lowest terms.

it would be 2/3

Remember, when you write a fraction is is part/whole. You want to know how many rolls are left so do the subtraction (15 to start with, 10 are used)...this will be your "part" or numerator. The amount you started with will be your "whole" or denominator. You can reduce them by dividing them both by 5.
