### How do you know whether to use common factors or multiples to solve a problem?

The hcf is useful in reducing fractions to their lowest terms and the lcm is useful in finding the lowest common denominator of fractions that have different denominators that need to be added or subtracted.

### How do you add mixed fractions with different denominators?

You make it into a improper fraction, then make a common denominator and remember to do what you did to the bottom to the top then solve

### When is it useful to find the LCM or GCF of two numbers to solve a problem?

When adding or subtracting fractions with different denominators and when reducing fractions to their lowest termsWhen adding or subtracting fractions with different denominators their lowest common multiple is needed and when reducing fractions to their lowest terms their greatest common factor is needed.

### What is a common denometer?

When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.

### Why do you use LCD to solve the addition and subtraction fractions?

Because you can't add or subtract fractions unless they have the same denominator, so when you run up against two fractions with different denominators, you have to find a single denominator that works for both of them. There are an infinite number of common denominators that you could use, but the easiest one to handle without making mistakes is going to be the smallest one, so it's worth knowing how to find it.

### what is the meaning of unrelated fraction?

To solve an unrelated fraction you must, numerator multiplied by the numerator and denominator multiplied by denominator. When dividing fractions with the different/unrelated denominators, it’s a little bit more complicated. What you have to do is flip (find the inverse) the second fraction then proceed as if your multiplying the fractions.

### How do you solve all fractions problems?

You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.

### How do you solve 1 and one third times 2 and one fourth times 3 and one fifth?

This can be done in different ways, but it is probably easiest to convert all the mixed fractions to improper fractions first. Then multiply all the numerators, and all the denominators. You can do simplifications either before multiplying, or after multiplying.

### How do you solve fractions?

You cannot solve fractions. There may be sums or products containing fractions or equations that can be solved. But fractions themselves cannot.

### How do you solve 2 square root 5 plus 4 square root 5?

It is: 6 square root 5 and it's just like adding fractions with the same denominators

### How do you solve adding fractions?

To add fractions with a common denominator, you simply add the numerators and keep the denominators the same. For instance, 1/7+3/7 = 4/7 If the denominators are different, you will need to find an equivalent fraction of one of the values that means the denominators can be equal. This is done by multiplying top and bottom of a fraction by the same amount. For instance, if we had 1/3 + 4/9, we would need to multiply top and bottom of the first fraction by 3. That gives us 3/9 + 4/9. Then the addition can be completed normally.

### How do you solve proper fractions?

You cannot solve proper fractions. You may be able to solve problems involving fractions but that is NOT the same thing. Furthermore, the solution methods depend on the problem.
