Question

if 1\3 of a number exceeds its 2\7 by 1, find the number​

Answer 1

Answer:21

Step-by-step explanation:et 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=21
