Anumber has the digits 8,4 and 3 to the nearest 10 the number rounds 440 what's the number ?
show me the solution

The number is 438

Step-by-step explanation:

We know that the number has the digits 8,4 and 3 and rounded to the nearest 10th the number is 440. Therefore, the number will have 3 digits and necessarily it will be an integer number.

The closest integer number to 440 which we can form with the digits 8,4 and 3 is 438.

Now, If we want to round the number 438 to the nearest 10th we need to pay attention to the number of the middle and the number at the right.

The middle number is 3 and to round the whole number we need to look for the value of the number of the right. If that value is 5 or more, we round the number to 440. If that value is less than 5 we round the number to 430.

The number at the right is 8. 8 is greater than 5. Therefore, we round 438 to 440.
