(A) 0.3
(B) 0.03
(C) 0.003
(D) 3
The answer is (B) 0.03.
Let’s perform the multiplication:
0.5 (multiplicand) x 0.06 (multiplier) = product
Here, we can ignore the decimal places for a moment and perform the multiplication like normal:
5 x 6 = 30
Now, since both the multiplicand and multiplier have one decimal place each, the product will have a total of two decimal places. So, we move the decimal point in our product (30) two places to the left:
30.00 –> Since we only need two decimal places, we round to the nearest hundredth: 0.03
Therefore, 0.5 x 0.06 = 0.03.
