Answer: 1.12

Step-by-step explanation:

Here 1.79 -0.67 = 1.12 ( if we subtract from the large  positive number to a minimum number then it's answer always should be positive value )

Now we are looking for the rounding figure with is very near of it which is 2 decimal or percentage value

For example :

1.444- 0.67 = 0.774 ( Here last digit is 4 so its round will be 0.77)

1.444-0.677 = 0.767 ( Here last digit is 7 so its round will be 0.77)

So we will round the value if it's last digit is greater than or equal to 5 value.
