Question

Please help me prove or disprove this: 'If a number's last digits are 1, 2, and 5, then the number is divisible by 125'

Answer 1

Yes but it depends what is it addtion or sub

Explanation:

Answer 2

False

Explanation:

This is not true

To disprove, here's a counter-example:

261 ends with 1 but is not divisible by 125.

261/125

(250+11)/125

250/125 + 11/125

2 11/125

Since there's a remainder of 11, 261 is not divisible by 125
