Hello
If 7.445 is rounded to one decimal would the answer be 7.4 or 7.5? Do we start rounding from the last number or the second 4 (in hundreth place)?
Thank you

You only need to look at the first digit you intend to drop. Here, that is the 4 in the hundredths place. That is, you're only looking at 7.44 if you want to round to tenths... 7.445 ≈ 7.4

If the number is rounded to one decimal place, consider the second decimal place only, i.e. consider 7.44….
The number is then rounded to 7.4.
The number is then rounded to 7.4.

If you round to the first decimal place, you look at the second decimal place.
7.44 rounds to 7.4
7.44 rounds to 7.4

I will go a long explanation. Once you get the idea right, you will be able to do quickly and in fewer steps.
1.
Start with last number, 5. When you drop it, its influence on 4 is nothing (Note: if it were 6 or any number larger than 5, it will convert 4 into 5 before dropping out).
2.
Now you are left with 7.44
3.
You are ready to drop last 4. Same logic applies for rounding up this time.
4.
Your answer is 7.4

7.4
It should be obvious that
7.445 - 7.4 is smaller than 7.5 - 7.445

7.4 I would look at the number to the right of the decimal. 0.445 < 0.500

7.4

Generally, it would be 7.45, because you're rounding the last digit or two decimal points.. UNLESS it's specified to be rounded earlier/later in the problem.

If you round the number after any decimal point, see the neglected number.If it is 5 or more than add one. Here it will be 7.4, If you want to retain the next number then it will be 7.45

Hi so as you start with a 4 figure amount it must be 7.5. if it was just 7.44 then it could be 7.4 however that last 0.005 makes all the difference.
