Question
0.43 x 0.2 =
- 0.086
- 0.0084
- 0.085
- 0.081
Hint:
In decimal multiplication, first we have to add the number of digits after the decimal point in both the numbers for example, in the given question two numbers whose product is asked is 0.43 and 0.2 so the sum of the digits after the decimal point in both the numbers is 3 ( two in 0.43, i.e., 43 and one in 0.2 ,i.e., 2). Then we perform normal multiplication of 0.43 and 0.2 (ignoring the decimal point) and in the product that we get we need to put the decimal point after 3 digits( i.e., the sum of digits that we found at first) from right. And we will get our required answer.
The correct answer is: 0.086
Step by step solution:
Given two decimal numbers whose product is to be found: 0.43 and 0.2
Now, we need to multiply the two decimal numbers
0.43
x 0.2
86 (we got the product by ignoring the decimal point)
Now, we have to place the decimal point after 3 digits from the right, i.e., 0.86 which is the required product of the two numbers.
Hence, option (a) is the correct option.

If each shirt costs $6.90 and you buy 5 of them, then the total cost is _______
Another approach to the question might be that we can just add $6.90 five times since 5 shirts are bought.
Therefore, the total cost = $ (6.90+6.90+6.90+6.90+6.90)
= $ 34.50
Thus, total cost would be $34.50 which is option (a)
