Solution
The correct option is B False Let's do 0.6×1.5
Step 1: Count the number of digits after decimal point for both the numbers and add them.i.e1+1=2
Step 2: Ignore a decimal point and perform the multiplication, as you would with whole numbers as follows Step 3: Now place a decimal point back.
0.6 and 1.5 have 2 digits after decimal. So, move the decimal point 2 places to the left in the product 0.6×1.5=0.90=0.9 (trailing zeroes after the decimal are not considered). Hence, there is only one digit after decimal and the statement is false.
