Answer 1

Appropriate Question:

The denominator of a rational number is greater than its numerator by 7. If the numerator is increased by 17 and denominator is decreased by 6, the new number formed becomes 2. Find the original number.

⠀

Given: The denominator of a rational number is greater than its numerator by 7.

❒ Let the numerator be x. And, the Denominator be (x + 7).

⠀

$\qquad\quad\boxed{\bf{\mid{\overline{\underline{\bigstar\: According\: to \; the\; Question \: :}}}}\mid}$

⠀

If the numerator is increased by 17 and denominator is decreased by 6, the new number formed becomes 2.

⠀

Therefore,

Numerator, x = (x + 17)

Also,

Denominator, (x + 7 - 6) = (x + 1)

⠀

Now,

⠀

$:\implies\sf \dfrac{\Big(x + 17 \Big) }{\Big(x + 1 \Big)} = 2 \\\\\\:\implies\sf \Big(x + 17 \Big) = 2 \Big(x + 1 \Big) \\\\\\:\implies\sf x + 17 = 2x + 2\\\\\\:\implies\sf 2x - x = 17 - 2\\\\\\:\implies{\underline{\boxed{\frak{\pink{x = 15}}}}}\;\bigstar$

⠀

Hence,

⠀

Numerator, x = 15

And, Denominator, (x + 7) = 15 + 17 = 22

⠀⠀⠀⠀⠀⠀

$\therefore{\underline{\sf{Hence, \: the\; original\; number\;is \; \bf{\dfrac{15}{22}}.}}}$

Answer 2

Step-by-step explanation:

solution -h=V/ l x b

= 7x6 =48

84-48 =36 height

answer is 36 height
