1.25%0.5=0.25 How we got this answer?

Answer 1

The % operator means the *remainder* after the division is executed.

In your example 1.25%0.5 means the remainder after 1.25 is divided by 0.5. It is easy to see that 0.5 goes *fully* into 1.25 two times, which makes 1. The remainder is 0.25.

Answer 2

7%3 would be 1 because 3 goes into 7 twice (making 6) and the remainder is 1.

Answer 3

0.5 × 3 = 1.5
0.5 × 2 = 1

1 + ? = 1.25
? = 1.25 -1 = 0.25
