Question

If 1/3 of a number exceeds its 2/7 by 1 , find the number
Please give step by step explanation

Answer 1

Step-by-step explanation:

Let the number =x

1/3 of a number = x/3

2/7 of the number = 2x/7

given

1/3 of a number exceeds its 2/7 by 1

x/3 - 2x/7 =1

do the lcm

lcm = 3*7 =21

(7x-6x)/21 =1

⇒x/21 =1

∴ x= 21

required number = x =
