How do you triple a fraction?
Doubling or tripling recipes means taking the fractions and multiplying the numerators. The students will see that it is easy to multiply the whole numbers and then multiply the numerators of the fractions.
What is half of 3/4 in fraction?
Janet, taking half of a fraction involves doubling the denominator. Half of 3/4 is 3/8.
What’s a double fraction?
If you double the numerator in a unit fraction, that means you have two unit fractions. For example, doubling frac13 means taking frac13 two times which is frac23. If you double the numerator of any fraction, you double the number of unit fractions.
How do you cross multiply?
Well, to cross multiply them, you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. Then you multiply the numerator of the second fraction times the number in the denominator of your first fraction, and you write that number down.

What is Half of one and Half?
One half plus one half equals 1. Mathematically, one half is equal to 1/2. We can only add fractions that have the same denominator.
How do you add 2 fractions with different denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
What is an mixed fraction?
More specifically, a mixed fraction is simply an improper fraction written as the sum of a whole number and a proper fraction. For example, the improper fraction 3/2 can be written as the equivalent mixed fraction 1-1/2 (read aloud as “one-and-a-half” or “one-and-one-half”).
How do you add two fractions together?
Here’s the traditional way to add fractions with two different denominators:
- Find the LCM of the two denominators. Suppose you want to add the fractions 3/4 + 7/10.
- Increase the terms of each fraction so that the denominator of each equals the LCM.
- Substitute these two new fractions for the original ones and add.
How do we multiply fractions?
There are 3 simple steps to multiply fractions
- Multiply the top numbers (the numerators).
- Multiply the bottom numbers (the denominators).
- Simplify the fraction if needed.
Why do we multiply fractions?
What Does It Mean to Multiply by a Fraction? When you multiply a number by a fraction, you are finding part of that number. For example, if you multiply 6 by 1/2, you are finding 1/2 of 6.Anytime you’re multiplying a number by a fraction, you’re finding part of that number.
