How to divide by 0.5

A quick method to division by 0.5 or ½ is to double the number (or multiply number through 2). The reason for this is that 2 halves go into a whole. If girlfriend still can’t check out why you dual the number, just think about an easy example, such as, 3 ÷ 0.5. Go with your multiples that 0.5 until you reach 3:

0.5, 1, 1.5, 2, 2.5, 3...

You are watching: 0.5*0.5*0.5*0.5


As you have the right to see 3 is the 6th multiple of 0.5, for this reason the answer come 3 ÷ 0.5 is 6.

Another thing to psychic is that as soon as you divide by a decimal in between 0 and 1 the price is larger than the number that you started off with.

Let’s look at at part harder questions that involve splitting by 0.5:

Example 1

Work out the answer come 26 ÷ 0.5.

All you have to do is dual the number, as dividing by 0.5 is the exact same as multiplying by 2:

26 ÷ 0.5 = 26 × 2 = 52.

Example 2

Work out the answer to 57 ÷ 1/2:

Again every you should do is twin the initial number, as separating by ½ is the same as multiply by 2:


57 ÷ ½ = 57 × 2 = 114.


Example 3

Find the value of 428 ÷ 0.5:

Again, twin the number you space dividing:

428 + 428 = 856.

Example 4

Work the end an calculation to 726.854 ÷ 0.478.

When carrying out an calculation round every the numbers off to 1 far-ranging figure:

726.854 = 700

0.478 = 0.5

All you have to do now is work-related out 700 ÷ 0.5. Similar to the critical 3 examples this can be done by multiplying 700 by 2:

700 ÷ 0.5 = 700 × 2 = 1400.

So an estimate to the calculation 726.854 ÷ 0.478 is 1400.

Example 5

How plenty of pieces of timber 0.5m long can be reduced from a plank of lumber of size 9m.


Here you need to work the end how many 0.5’s go into 9:

9 ÷ 0.5 = 9 × 2 = 18

So 18 piece of wood deserve to be reduced from the plank that wood.
