The first digit of a six digit number is nine. if this night is moved to the end of the number, the new six digit number is only a quarter of the original number. find the original number.

Original number: 923076

Step-by-step explanation:

Original number = 9 let's use x to represent

Then the original number = 900000 + x

when 9 be moved to the end 9 i.e. 10x + 9

900000 + x = 4 * (10x + 9)

900000 + x = 40x + 36

39x = 899964

x = 23076

Original number: 923076

check: 230769 x 4 = 923076 correct
