### If the divisor is not a whole number, move the decimal point to .... to make it a whole number.

• A.

Right

• B.

Left

• C.

Top

• D.

Middle

Correct Answer
A. Right
Explanation
If the divisor is not a whole number, moving the decimal point to the right will make it a whole number. This is because moving the decimal point to the right increases the value of the number, and by doing so, we can eventually reach a point where the decimal part becomes zero, resulting in a whole number.

• A.

Multiplication

• B.

Addition

• C.

Subtraction

• D.

### To divide decimal numbers, put decimal point directly ... decimal point in the dividend.

• A.

Above

• B.

Below

• C.

Middle

• D.

None

Correct Answer
A. Above
Explanation
When dividing decimal numbers, the decimal point in the quotient should be placed directly above the decimal point in the dividend. This is because the decimal point represents the position of the decimal in the number. By aligning the decimal points, we ensure that the quotient retains the same decimal place value as the dividend.

Rate this question:

### To divide decimal numbers, multiply the divisor by as many ...

• A.

10's

• B.

20's

• C.

5's

• D.

30's

Correct Answer
A. 10's
Explanation
To divide decimal numbers, you need to move the decimal point of the divisor and dividend to the right until the divisor becomes a whole number. By multiplying the divisor by 10's, you are essentially moving the decimal point one place to the right. This ensures that the divisor becomes a whole number, allowing for easier division.
