# How do you do simple equations with fractions?

## How do you do simple equations with fractions?

To solve equations with fractions we can follow this method:

1. Find the LCD of the denominators.
2. Multiply all the terms of the equation by the LCD of the denominators.
3. For each term of the equation, divide by the HCF of the denominators of that term and the LCD.
4. Multiply the factors that remain in each term.

How do you get a fraction out of an equation?

To remove fractions: Since fractions are another way to write division, and the inverse of divide is to multiply, you remove fractions by multiplying both sides by the LCD of all of your fractions.

What is golden rule of fractions?

The mathematical golden rule states that, for any fraction, both numerator and denominator may be multiplied by the same number without changing the fraction’s value.

### When adding or subtracting fractions you must first?

In order to add or subtract, fractions must have common denominators. To add fractions, if the denominators are the same, we simply add the numerators and keep the same denominators.

What are the rules to solve an equation?

A General Rule for Solving Equations

• Simplify each side of the equation by removing parentheses and combining like terms.
• Use addition or subtraction to isolate the variable term on one side of the equation.
• Use multiplication or division to solve for the variable.

How to solve equations with fractions?

How to solve equations with fractions Step 1: Find the least common denominator Step 2: Multiply the least common denominator Step 3: Simplify the equation Step 4: Simplify until there’s one term on both sides Step 5: Divide the coefficient on both sides Examples of how to solve equations with fractions

## How do you subtract a fraction from a whole number?

For the first fraction, 15 divided by 5 = 3 and 3 times 3 = 9. The result is 9/15. For the second one, 15 divided by 3 = 5 and 5 times 1 = 5. The result is 5/15. The last step is to subtract the adjusted numerators: 9 minus 5 = 4. The resulting fraction equals 4/15. Let’s now look at the case when we need to subtract a fraction from a whole number.

How do you get rid of fractions?

In the next example, you will see two fractions. Since they have the same denominator, we will multiply by the denominator and get rid of both fractions. Did you notice how multiplying by 2 (the denominator of both fractions) allowed us to get rid of the fractions? This is the best way to deal with equations that contain fractions.

Are fractions difficult?

I know fractions are difficult, but with these easy step-by step instructions you’ll be solving equations with fractions in no time. Do you start to get nervous when you see fractions?
