Question

Write 73.654 correct to 1 decimal place

Answer 1

To round 73.654 to 1 decimal place, we round up the first decimal place from 6 to 7 because the second decimal place is 5, resulting in 73.7.

Step-by-step explanation:

To write the number 73.654 correct to 1 decimal place, you look at the second decimal place, which in this case is 5. If this number is 5 or greater, you round up the first decimal place. Since it is 5, we round up the 6 to 7. Therefore, 73.654 correct to 1 decimal place is 73.7.

In general, the steps for rounding to a given number of decimal places involve:

1. Identifying the digit at the given decimal place.
2. Looking at the next digit to the right (if there is one).
3. If the next digit is 5 or more, increase the digit in the rounding place by one. If it is less than 5, leave the digit in the rounding place as is.
4. Remove all digits to the right of the rounding place.

An example of rounding a different number to 1 decimal place would be rounding 1.74 to 1.7, because the digit in the second decimal place is 4, which is less than 5, so the first decimal place stays the same.
