How much you need to add to 243 to make it divisible by 10?
To make 243 divisible by 10, we need to find the nearest multiple of 10. The nearest multiple of 10 less than 243 is 240. To make 243 divisible by 10, we need to add 240 + 3, which equals 243. Therefore, we need to add 3 to 243 to make it divisible by 10.
Why do you only need to look at the last two digits of a number to know if it is divisible by 4?
If a number is divisible by 4, the last two digits are divisible by 4. For example, the number 314 is not divisible by 4, but 316 is divisible by 4, because 16 is divisible by 4.

What is the smallest sum of money that can be added to 2.45 to make it exactly divisible by 9?
To find the smallest sum of money that can be added to 2.45 to make it exactly divisible by 9, we first need to determine the remainder when 2.45 is divided by 9. 2.45 can be written as 245/100. When 245 is divided by 9, the remainder is 8. To make 2.45 exactly divisible by 9, we need to add the difference between 9 and the remainder, which is 9 - 8 = 1. Therefore, the smallest sum of money that can be added to 2.45 to make it exactly divisible by 9 is $0.01.
