Question

Solve the following $0.9 \times 100$

Answer 1

Hint: The mathematical operation which we are going to use to solve the problem is multiplication.
Since multiplicand refers to the number multiplied. Also, a multiplier refers to multiplying the first number. Have a look at an example; while multiplying $0.9 \times 100$the number $0.9$ is called the multiplicand and the number $100$ is called the multiplier. The most important concept is that we studied the multiplication table in our school days.

Complete step by step answer:
Since from the given we ask to find the value of $0.9 \times 100$. Which is in decimal format.
Applying the multiplication operation with the number $10$ for the first approach then we get $0.9 \times 100 = 9 \times 10$
Again, applying the multiplication operation with the number $10$ for the first approach then we get $0.9 \times 100 = 9 \times 10 \Rightarrow 90$ which is the required answer.
We can also solve the given as converting the decimal into fraction as $0.9 = \dfrac{9}{{10}}$
Then we get $\dfrac{9}{{10}} \times 100 = 9 \times 10 = 90$ by using the division operation also.
Hence the answer we found is $0.9 \times 100 = 90$

Note:
The other three operations are addition, subtracting, and division.
Subtraction operation, which is the minus of given two or more than two numbers, but here comes with the condition that in subtraction the greater number sign represented in the number will stay constant example $2 - 3 = - 1$
The addition is the sum of given two or more than two numbers, or variables and in addition, if we sum the two or more numbers then we obtain a new frame of the number will be found like $0.9 + 100 = 100.9$
The process of the inverse of the multiplication method is called division. Like $x \times y = z$is multiplication thus the division sees as $x = \dfrac{z}{y}$. Like $\dfrac{{0.9}}{{100}} = 0.009$
