Dividing decimal

Example: Divide 9.1 by 7

Ignore the decimal point and use Long Division:

13 7 )91    9    7    21    21     0

Put the decimal point in the answer directly above the decimal point in the dividend:

1.3 7 )9.1

The answer is 1.3

Dividing by a Decimal Number

But what if you want to divide by a Decimal Number?
The trick is to convert the number you are dividing by to a whole number first, by shifting the decimal point of both numbers to the right:

Now you are dividing by a whole number, and can continue as normal.
It is safe to do this if you remember to shift the decimal point of both numbers the same number of places.

Example 2: Divide 5.39 by 1.1

You are not dividing by a whole number, so you need to move the decimal point so that you are dividing by a whole number:

move 1
5.39		53.9
1.1		11
move 1

You are now dividing by a whole number, so you can proceed:
Ignore the decimal point and use Long Division:

049 11 )539     5     0     53     44      99      99       0

Put the decimal point in the answer directly above the decimal point in the dividend:

04.9 11 )53.9

The answer is 4.9

dividing fractions

There are 3 Simple Steps to Divide Fractions:

Step 1. Turn the second fraction (the one you want to divide by) upside-down (this is now a reciprocal).

Step 2. Multiply the first fraction by that reciprocal Step 3. Simplify the fraction (if needed) Example 1 1 ÷ 1 2 6 Step 1. Turn the second fraction upside-down (it becomes a reciprocal): 1  becomes  6 6 1 Step 2. Multiply the first fraction by that reciprocal: 1 × 6 = 1 × 6 = 6 2 1 2 × 1 2 Step 3. Simplify the fraction: 6 = 3 2
