Question

Express 84 by 147 as a rational number with denominator 7

Answer 1

a rational number is a number which can be represented in the form p by q and p and q both belong to the set of integers where q is not equal to zero

so here is your answer hope this helps

Answer 2

Given:

$\frac{84}{147}$

To find:

The rational form of 84/147 with denominator 7.

Solution:

The rational form of 84/147 with denominator 7 is 4/7.

To answer this question, we will follow the following steps:

First of all, we should know that a number is said to be a rational number if it can be written in the form of p/q where q is not equal to 0.

Now,

as given in the question, we have

$\frac{84}{147}$

We need to write the above number in a rational number that has a denominator 7.

So, let the numerator of a required rational number be x.

So,

Required rational number

$= \frac{x}{7}$

So,

$\frac{84}{147} = \frac{x}{7}$

On cross-multiplication, we get,

$\frac{84 \times 7}{147} = x$

$\frac{84}{21} = x$

$x = 4$

Hence, the required rational number is 4/7.
