_______

**Possible Answers:**

**Correct answer:**

To find out what number to subtract 0.7 from to get 2.8, just do the opposite - add 0.7 to 2.8.

### Example Question #2 : Fluently Add, Subtract, Multiply, And Divide Multi Digit Decimals: Ccss.Math.Content.6.Ns.B.3

Find the **sum** of 2.4, 55, and 6.21.

**Possible Answers:**

**Correct answer:**

To find the sum, you need to add. Line up all numbers vertically. Since one number has a decimal to the tenths place, one has a decimal to the hundredths place, and one has no decimal, be extra careful to line up the digits correctly! To help you, add a zero to the end of 2.4, and add two zeroes to the end of 55 so that all the digits line up correctly.

Now, add down each column, starting on the right side and moving to the left.

The sum is 63.61.

### Example Question #7 : Fluently Add, Subtract, Multiply, And Divide Multi Digit Decimals: Ccss.Math.Content.6.Ns.B.3

Multiply:

**Possible Answers:**

**Correct answer:**

We ignore the decimals for the time being, multiplying:

Since, between them, the two original factors have a total of two digits to the right of their decimal points, we place the decimal point in the product so that there are two digits to the right. This yields:

### Example Question #8 : Fluently Add, Subtract, Multiply, And Divide Multi Digit Decimals: Ccss.Math.Content.6.Ns.B.3
