In mathematics, ten as it base is as called system of decimals numbers. The natural numbers using the base-10 numeral system specified as decimal notation. A dot with a decimal number, like to present in 41.654.
Decimals numbers are used in arithmetic operations. One of the arithmetic operations is multiplying. Generally multiply is scaling a number by another by using multiplication. In the topic, we are going to discuss about multiplying two decimals.
Examples Problem for Multiplying Two Decimals:
1. Multiply the two decimals given numbers are, 0.04 by 2.2.
Solution:
Given decimals numbers are, 0.04 'xx' 2.2,
= 0.04 'xx' 2.2
Multiply the numbers without decimal points,
Then we get the value is,
= 4 'xx' 22
= 88
In this problem, 0.04 has 2(two) decimal points and 2.2 has 1(one) decimal points,
So, given multiplying two decimals answer has 3(three) decimal places,
= 0.088
Answer is 0.088.
2. Multiply the two decimals given numbers are, 0.12 by 4.5.
Solution:
Given decimals numbers are, 0.12 'xx' 4.5,
= 0.12 'xx' 4.5
Multiply the numbers without decimal points,
Then we get the value is,
= 12 'xx' 45
= 540
In this problem, 0.12 has 2(two) decimal points and 4.5 has 1(one) decimal points,
So, given multiplying two decimals answer has 3(three) decimal places,
= 0.540
Answer is 0.540.
3. Multiply the two decimals given numbers are, 1.23 by 3.6.
Solution:
Given decimals numbers are, 1.23 'xx' 3.6,
= 1.23 'xx' 3.6
Multiply the numbers without decimal points,
Then we get the value is,
= 123 'xx' 36
= 4428
In this problem, 1.23 has 2(two) decimal points and 3.6 has 1(one) decimal points,
So, given multiplying two decimals answer has 3(three) decimal places,
= 4.428
Answer is 4.428.
4. Multiply the two decimals given numbers are, 3.45 by 8.56.
Solution:
Given decimals numbers are, 3.45 'xx' 8.56,
= 3.45 'xx' 8.56
Multiply the numbers without decimal points,
Then we get the value is,
= 345 'xx' 856
= 295320
In this problem, 3.45 has 2(two) decimal points and 8.56 has 2(two) decimal points,
So, given multiplying two decimals answer has 4(four) decimal places,
