Question

Why does the product of 3.4 x 0.5 have only one decimal place?

Answer 1

Explanation:

• Why does the product of 3.4 x 0.5 have only one decimal place?

when you multiply decimals, 3.4 x 0.5 = 1.70, the zero can be removed because it has no value, so the result is 1.7

Answer 2

1.7.

Explanation:

3.4 x 0.5

= 3 x 0.5 + 0.4 x 0.5

= 1.5 + 0.20

= 1.70

We do not include the 0 so the answer has one decimal place (1.7).

(There's no point in saying 1 and 7 tenths and 0 hundredths!)
