Question

Judy claims that she can find 0.5 x 2.4 by dividing 2.4 into two equal parts. Is she correct? Draw a decimal model to explain

Answer 1

Yes because 2.4 in half is 1.2

Answer 2

Judy's claim to divide 2.4 by 2 is the same as multiplying 2.4 * 0.5 is:

• Correct.

Explanation:

Multiplying a number by 0.5 (whose fractional is 1/2) is the same as dividing this number by 2, this case is very easy to identify by making different examples in which said decimals and integers are used, checking that the result is the same:

EXAMPLES.

1. 12*0.5 = 6

12/2 = 6

2. 3*0.5 = 1.5

3/2 = 1.5

3. 5.5*0.5 = 2.75

5.5/2 = 2.75

As you can see in the previous examples, performing the operation by both methods is correct.
