Question

I am a number smaller than 4 with only 1 decimal place. I am 4 when rounded to the nearest whole number.
The digit in my tenths place is even.
The digit in my ones place is 5 less than the digit in the tenths place. What number am I?

Answer 1

Answer:

How do you round to 4 decimal places?

Ans- To round the number off to 4 decimal places, put a line in after the first 4 digits after the decimal point. If the number after the line is less than 5, round the number down (keep it the same). If the number is 5 or above round the number upwards. So in example 1 you need to round 4.17356 to 4 decimal places.

The digit in my ones place is 5 less than the digit in the tenths place.

We have to Find: What number am I?

To round the number off to 4 decimal places, put a line in after the first 4 digits after the decimal point. If the number after the line is less than 5, round the number down (keep it the same). If the number is 5 or above round the number upwards. So in example 1 you need to round 4.17356 to 4 decimal places.

Final Answer: To round the number off to 4 decimal places, put a line in after the first 4 digits after the decimal point. If the number after the line is less than 5, round the number down (keep it the same). If the number is 5 or above round the number upwards.
