6th grade Q1

A mixed decimal is a number that consists of a whole number part and a decimal part, like in 5.6478. It combines the two into a single value. The "opposite" of a mixed decimal is a pure decimal, that's only got the decimal part, like 0.6478.

Whether you're working with mixed decimals or pure decimals, the same rules apply.

So, focus on aligning and correctly handling the decimal points, and the "mixed" nature of the decimal doesn't create any extra challenges!

When adding mixed decimals, follow these steps:

Example:

1. Line up the decimal points

Adding zeros at the end of 2.34 makes it easier to add because it helps the numbers match up. The value stays the same.

2. Add each place value starting from the right
Ten-thousandths place: $8+0=8$

Thousandths place: $7+0=7$

Hundredths place: $4+4=8$

Tenths place: $6+3=9$

Ones place: $5+2=7$

3. Final Answer

There was no need to regroup, as no column had a sum greater than 9.
