Question

A number rounded to the nearest 10 is 550. What is the smallest possible number it could be?

Answer 1

Answer:

Let's now consider the number 65. Do you think it will round down to 60 or round up to 70?

That's right, it will round up to 70. This means that all the numbers between 65 and 74 will round off to 70 when rounded to the nearest ten.

Let's look at rounding off a 3-digit number to the nearest ten.

I will use the number 144 to illustrate.

Underline the last 2 digits - 144.

The digit 4 is in the tens place, so 144 will become either 140 or 150 after rounding off to the nearest ten.

Draw a number line with 3 numbers on it: 140, 145 and 150. (Both possible rounded off numbers and the number in the middle.)
