You can use the LCD Calculator to find the least common denominator for a set of fractions For your first fraction find what number you need to multiply the denominator by to result in the least common denominator Multiply the numerator and denominator of your first fraction by that number Repeat Steps 3 and 4 for each fraction.

How to work out fraction multiplication sums. Multiply the top numbers the numerators. It also has commands for splitting fractions into partial fractions combining several fractions into one and cancelling common factors within a fraction. This is equal to the digit sum of 3993 which is 6.

When you want to multiply fractions multiply the 2 numerators together first and write it on top. You can do this because any number divided by one is always equal to itself Now because you are multiplying a fraction by a fraction you can apply the rule and solve as follows. The algebra section allows you to expand factor or simplify virtually any expression you choose.

There are 3 simple steps to multiply fractions 1. Enter the fraction you want to simplify. To get 13.

Multiply Fractions Calculator Step 1. For example if you want to solve 45 x 12 multiply the numerators for 4 x 1 4. Multiply the bottom numbers the denominators.

Insert a decimal point in the product so it has the same number of decimal places equal to the total from step 1. Simplify your answer if you can so it is in the lowest terms. First add then multiply and finally subtract.

2 1 3. For instance if you have 50 cents half of a dollar and you want to multiply it by a half then you end up with 25 cents a quarter of a dollar. To multiply two fractions then simply multiply the numerators and multiply the denominators to get the product.

Multiply the 3 by the top number 469 and write this number next to the zero. The number 6 is twice as big as 3 so to make the bottom numbers the same we can multiply the top and bottom of the first fraction by 2 like this. To get 12.

Simplify the fraction if needed. If there were more numbers we would add more rows and continue to add more zeros. To work this out we can work from left to right.

Order of precedence Suppose we have this expression. Take a Digit from the Multiplier Take a digit from the multiplier starting from the left. Multiply by the Multiplicand.

And use the rules for adding subtracting multiplying and dividing them. Lets take an example so we get how simple it really is. Thats quite a mouthful.

The number on the bottom was 432 we would add two zeros in. 363 x 11 3993. For example if there were a 4 in the hundreds spot ie.

Start by rewriting the whole number 3 in this example as a fraction 31 as follows. 3 x 2 6. The digit sum of 363 is 3.

Ignore the decimals and right align the numbers one on top of the other as if they were integers. Then multiply the denominators together and write it on the bottom of the fraction. The digit sum of 11 is 2.

Multiply the single digit and from the multiplier and the multiplicand to. Multiply the numbers using long multiplication. The multiply fractions calculator will multiply fractions and reduce the fraction to its simplest form.
