iv. 2.0009x1.900
the question .answer.....explain the formula and answer solve it
Answers
When we multiply two decimal numbers, we follow the following steps :-
a) Count the total number of digits (of the two numbers together).
b) Multiply the numbers simply (like you do normally).
c) In the product obtained in step b), put the decimal point before the no. of digits counted in step a).
You get the answer!
Let's solve your questions.
iii) 3.04 × 6.04
a) Count the total number of digits after the decimal point (of the two numbers together).
The no. of digits after the decimal point in 3.04 is 2.
The no. of digits after the decimal point in 6.04 is 2.
Therefore, the total no. of digits after the decimal point (of the two numbers together) is 4.
b) Multiply the numbers simply (like you do normally).
Remove the decimal points and multiply the numbers.
304 × 604 = 183616
c) In the product obtained in step b), put the decimal point before the no. of digits counted in step a).
The product is 183616.
The number of digits after the decimal point (counted in a)) is 4.
Put the decimal point before 4 digits in the product.
18.3616
Hence, your answer is 18.3616. (3.04 × 6.04 = 18.3616)
iv) 2.0009 × 1.900
(1.900 = 1.9)
Therefore, you can write 2.0009 × 1.9.
a) Count the total number of digits after the decimal point (of the two numbers together).
It is 5.
b) Multiply the number simply (like you do normally).
Remove the decimal points and multiply the numbers.
20009 × 19 = 380171
c) In the product obtained in step b), put the decimal point before the no. of digits counted in step a).
The product is 380171.
The number of digits after the decimal point (counted in a)) is 5.
Put the decimal point before 5 digits in the product.
3.80171
Hence, your answer is 3.80171. (2.0009 × 1.9 = 3.80171)
