How to subtract a fraction

(<1) Problem:Me and my sister shared a box of candy. I ate 1/3 of it and she ate 2/5 of it. How much did we eat in total?

(<1) Problem:I went to the mall with a friend. I spent 6/8 of my money, and she spent 3/5 of her's. If we started with the same amount of money, how much more did I spend than her?

An improper fraction is when the numerator is greater than the denominator.Since a fraction is part of a whole, when the numerator is greater than the denominator,it means it is over one whole,therefore it is improper.

You reduce fractions because1: It's easier to imagine or picture it. For example, if I say 1/3, it's easier to picture that, but if I say 13/39, it's harder to know how much that is.2: It's easier to find the least common multiple with a smaller denominator and another denominator when you're subtracting, adding, or multiplying fractions.

To reduce fractions, you have to find the least common factor of both the numerator and the denominator. Then, you would have to divide the numerator and the denominator by that number, and your answer to both numbers is the new reduced fraction.

Fractions are numbers that represent part of a whole.Fractions consist of the numerator, being the top number,and the denominator, being the bottom number.Numerator --> 1/2 <-- Denominator

A mixed fraction is a combinationof a whole number and a fraction.

How to multiply a fraction

Less than 1When subtracting fractions, you'll need to find a common denominator.In order to to find one, you will need to multiply the 2 denominators by each other. Then, whatever you multiplied the denominator by, multiply the numerator with the same number. Afterwards, simply subtract one numerator from the other, but not the denominators.Remember to reduce your answer after.Greater than 1In order to subtract fractions greater than one, just separate the whole numbers from the fractions. Then subtract those numbers from each other. Once you're done subtracting the fraction parts, simply add the whole number afterwards.

Problem: A daughter was buying flowers for her mom for Mother's Day.If each flower was 3/4 of a dollar, and she bought 8 flowers, how much did she spend?

When you're multiplying a fraction, you only need to multiply the numerator. You keep the denominator the same. Once you have multiplied the numerator, convert your answer to a mixed fraction, and always remember to reduce it. :)

Less than 1When adding fractions, you'll need to find a common denominator.In order to to find one, you will need to multiply the 2 denominators by each other. Then, whatever you multiplied the denominator by, multiply the numerator with the same number, Afterwards, simply add the numerators together, but not the denominators.Remember to reduce your answer after.Greater than 1In order to add fractions greater than one, just separate the whole numbers from the fractions. Then add those numbers together, and put it aside. Once you're done adding the fractions, simply add the whole number afterwards.

(>1) Problem:Fionna and I were eating cookies. She ate 3 2/3 cookies, and I ate 2 4/7 cookies. How many more cookies did she eat than me?

(>1) Problem:My family is going on a vacation. My parents have2 4/8 of suitcases filled and my sister and I have1 3/6.How many suitcases will we need in total?
