Question

four fifths of a number is more than two fifths of the number by two. Find numbers​

Answer 1

Answer:

Let us assume the number as x

Then,

${\frac{4x}{5 } = \frac{2x}{5} + 2}$

${ \frac{4x}{5} = \frac{2x + 10}{5} }$

$4=2+10$

$4x - 2x = 10$

$2x = 10$

$x = \frac{10}{2} = 5$

$x = 5$

Answer 2

Answer :

Therefore,

• The number is 5 .

Step-by-step-Explaination :

Step 1 :-

In first Step , Assume the number :-

So, let's Assume

• Let the Number be X .

Step 2 :-

In second Step we need to understand it nicely ! .

So, let's do it ..

Here , Given is four - fifth of a number is more than two - fifth of the number by two . Means , Four - Fifth of any number is more than Two - fifth of that same number by twice . So , now form equation and solve for X and you with get the numbers .

So , now our next step is ..

Step 3 :-

In the third Step we need to form the equation and solve it !! .

So , the equation thereby formed is

A.T.Q ,

$\rm \: \dfrac{4x}{5} = \dfrac{2x}{5} + 2$

Hence , now this equation is needed to be solved :-

Doing multiply of 5 and 2 and writing in Numerator of R.H.S .

$: :\implies \rm \: \dfrac{4x}{5} = \dfrac{2x}{5} + 2 \times 5$

$::\implies \rm \: \dfrac{4x}{5} = \dfrac{2x + 10}{5}$

Now , can you Notice one thing in both R.H.S and L.H.S side we are having our denominator same that means only we will have to remove them . Therefore ,

$::\implies \rm \: {4x} = {2x + 10}$

Bringing 2x to L.H.S and so, Sign changes from positive to negative.

$::\implies \rm \: {4x - 2x} = { 10}$

$::\implies \rm \: { 2x} = { 10}$

Now , taking 2 to R.H.S and dividing by 10 .

$::\implies \rm \: { x} = \cancel \dfrac{ 10}{2}$

$::\implies \rm \: \bf { x} = 5 \: \star$

Question :

Four fifths of a number is more than two fifths of the number by two. Find numbers

➢ Hence ,

• The number is 5 .
