Question:

The product of two fractions is 30 ⅓. One of them is 5 ⅔.  Find the other?

Basic idea:

In this problem we have the product of two fractions that is 30 ⅓.One of the number is given that is 5 ⅔. We need to find the other number.To solve this problem we need to assign the other fraction as x.By multiplying  5 ⅔ with x we will get 30 ⅓.We can solve for x by dividing 30 ⅓ by 5 ⅔.

Let the required second fraction be "X"

One of the fraction  =  5 ⅔

Product of two fractions = 30 ⅓

                     5 ⅔ x X  = 30 ⅓

Now we have to change the mixed fraction as improper fraction

                (15+2)/3 x X = (90+1)/3

                   (17/3) x X = 91/3

                               X = 91/3 ÷ (17/3)

Now we are going to change this division as multiplication.So that we have to write the second fraction as its reciprocal.The first fraction has to be written as it is.

                               X = (91/3) x (3/17)

                               X = (91x3)/(3x17)

The numerator and denominator 3 can be simplified using 3 times table.

                               X =  91/17

So the final answer is  91/17 .

“Mathematics, without this we can do nothing in our life. Each and everything around us is math.

Math is not only solving problems and finding solutions and it is also doing many things in our day to day life. They are:

It subtracts sadness and adds happiness in our life.

It divides sorrow and multiplies forgiveness and love.

Some people would not be able accept that the subject Math is easy to understand. That is because; they are unable to realize how the life is complicated. The problems in the subject Math are easier to solve than the problems in our real life. When we people are able to solve all the problems in the complicated life, why can we not solve the simple math problems?

Many people think that the subject math is always complicated and it exists to make things from simple to complicate. But the real existence of the subject math is to make things from complicate to simple.”
