Multiplication Formula





In this page multiplication formula we can find basic formulas in addition, subtraction, multiplication and division using fraction. By using this method we can easily add, subtract, multiply and divide any two fractions.

Difference:

If we want to multiply two fractions we have to multiply the numerators with numerators and denominator with denominator. If it is possible to simplify we have to do that and show the answer in the simplified form.

We have also given worksheets for each category of topics. By practicing this worksheets you can get more knowledge. These are the most basic topics in math. Students must practice this kind of worksheets. The students who are in the grade of elementary must practice these kinds of worksheets to get more knowledge in math. In this page you can get a clear idea in this topic and you have worksheets which consist of five question with clear steps has given.

Multiplication formula


ab x cd = (a x c) (b x d)


To understand this topic much better we have given some examples using  formula.

Example 1:

Multiply (5/6) x (3/8)

Solution:

Now let us compare the given two fractions that is 5/6 with a/b and 3/8 with c/d. The formula to multiply two fractions is ab/cd.

             = (5/6) x (3/8)

             =  (5x3)/(6x8)

             = 15/48

We can simplify this using 3 times table. So we will get 5/16.    

Example 2:

Multiply (1/17) x (5/8)

Solution:

Now let us compare the given two fractions that is 5/6 with a/b and 3/8 with c/d. The formula to multiply two fractions is ab/cd.

             = (1/17) x (5/8)

             =  (1x5)/(17x8)

             =  5/136

We can simplify this. So the final answer is 5/136    

Example 3:

Multiply (8/7) x (15/18)

Solution:

Now let us compare the given two fractions that is 5/6 with a/b and 3/8 with c/d. The formula to multiply two fractions is ab/cd.

             = (8/7) x (15/18)

             =  (8x15)/(7x18)

             =  120/126

We can simplify this using 2 times table. So the final answer is 60/63
