Solve the following exercise:
First we will break down each of the factors in the exercise into a whole number and its remainder:
Now we'll combine only the whole numbers:
Then we'll calculate the remainder:
Finally, we are left with the following:
22.1
Choose the correct writing form:
Separating makes the calculation easier and clearer! Instead of working with mixed decimals, you can add 8+5+8=21 and 0.5+0.2+0.4=1.1 separately, then combine for 22.1.
That's normal! In this problem, . The 1 gets added to your whole number total, and the 0.1 stays as the decimal part.
Yes! You can add vertically by aligning decimal points: 8.5 + 5.2 + 8.4. Both methods work, but separating helps you understand place value better.
Add the numbers in a different order or use the vertical method if you used separation. For example: 5.2 + 8.4 + 8.5 should still equal 22.1!
You'll get a completely wrong answer! For instance, treating 8.5 as 85 would give you 221 instead of 22.1. Always double-check your decimal point placement.
