Question

if ⅓ of a number exceeds 2/7 by 1, find the number

Answer 1

Hello !!!

Here is your answer.

Let the number be x.
Then, its 1/3 = x/3, and
2/7 of the same number = 2x/7

Given that ⅓ of number exceeds 2/7 of the number by 1....
So,
$\frac{x}{3} - \frac{2x}{7} = 1 \\ \frac{7x - 6x}{21} = 1$
x/21 = 1
Therefore, x = 21.

Hence the number is 21.

Answer 2

Heya !!



Let number be X.


1/3 of X = 1/3 × X = X/3



And,


2/7 of X = 2/7 × X = 2X/7.

According to question,


X/3 = 2X/7 + 1

X/3 = 2X + 7/7



7X = 6X + 21

7X - 6X = 21


X = 21.


Hence,


Number = X= 21
