|---|---|
| —– | —– |
Step 2: Align the Decimal Factors
Align the decimal level of the dividend and the divisor vertically. If the dividend does not have a decimal level, add one on the finish.

Draw a sequence of equal-sized rectangles above the dividend and divisor. These rectangles will signify fractions of the dividend and divisor.
| Dividend | Rectangles | Divisor | |||
|---|---|---|---|---|---|
| —–. | —– | ||||
Step 4: Divide the Dividend and Divisor
Divide the size of the rectangle on the dividend line by the size of the rectangle on the divisor line. This provides you with the quotient, which is the reply to the division drawback.
| Dividend | Rectangles | Divisor | |||
|---|---|---|---|---|---|
| —–. | —– | ||||
| Quotient | |||||
The best way to Train Dividing Decimals by a Complete Quantity Pictorially
Dividing decimals by an entire quantity generally is a difficult idea for college kids. To assist make it extra comprehensible, it’s useful to make use of pictorial representations. Here’s a step-by-step information on tips on how to train dividing decimals by an entire quantity pictorially:
