Answer 2

Answer:

when we subtract 1 from a number we get its pe

predecessor

Step-by-step explanation:

To know answer we take an example

when we subtract 1 from the number 9 we get,

Difference = 9-1

= 8

we know that 8 comes just before 9

i.e, 8 is called as predecessor of 9

what is predecessor?

In Maths, a predecessor of any number is the value that comes immediate before the original number.

For example, the predecessor of 20 is 19.

Now take another example

when we subtract 1 from the number 15 we get

Difference = 15-1

= 14

we know that 14 comes just before 15

i.e, 14 is called as predecessor of 15

Hence when we subtract 1 from a number we get

its predecessor
