Question

One- seventh of a number increased by 1 gives 2 hole 1/2

Answer 1

Answer:

$10 \frac{1}{2}$

Step-by-step explanation:

Let the number be x.

Hence, framing the equation:

$\frac{1}{7} x + 1 = 2 \frac{1}{2}$

$= > \frac{x}{7} + 1 = \frac{5}{2}$

$= > \frac{x}{7} = \frac{5}{2} - 1$

$= > \frac{x}{7} = \frac{5 - 2}{2}$

$= > \frac{x}{7} = \frac{3}{2}$

$= > x = \frac{3}{2} \times 7$

$= > x = \frac{21}{2}$

$= > x = 10 \frac{1}{2}$
