Answer 2

Answer :-

• The required number is 9/10.

To find :-

• The number which should be added to 17/5 to get 43/10.

Solution :-

Let the required number be "x".

It is given that :-

• When x is added to 17/5, we get 43/10.

Therefore,

$\hookrightarrow\tt\dfrac{17}{5} + x = \dfrac{43}{10}$

$\hookrightarrow\tt x = \dfrac{43}{10} - \dfrac{17}{5}$

$\hookrightarrow \tt x = \dfrac{43 \times 1 - 17 \times 2}{10}$

$\hookrightarrow\tt x = \dfrac{43 - 34}{10}$

$\hookrightarrow\tt x = \dfrac{9}{10}$

-----------------------------------------------------------

Verification :-

• To check our answer, let's add 9/10 to 17/5 and see whether we get 43/10.

$\hookrightarrow\bf \dfrac{17}{5} + \dfrac{9}{10}$

$\hookrightarrow\bf\dfrac{17 \times 2 + 9 \times 1}{10}$

$\hookrightarrow\bf\dfrac{34 + 9}{10}$

$\hookrightarrow\bf \dfrac{43}{10}$

We get :-

• 43/10 on adding 9/10 to 17/5.

Hence verified!
