It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part from the whole. It has two parts, numerator (number on the top) here, 45 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 2. A decimal is a way to represent the number that is not whole, using a (.) or a decimal to separate the whole part from the fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
45/2 in decimals can be written as 22.5. It is a terminating decimal, meaning it ends and does not repeat infinitely.
To get 45/2 in decimal, we will use the division method. Here, 45 is divided by 2 to convert it into a decimal form. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (45) will be taken as the dividend and the denominator (2) will be taken as the divisor.
Step 2: Divide 45 by 2. 2 goes into 4 two times (2 × 2 = 4).
Step 3: Subtract 4 from 4 gives 0, and bring down the next digit, which is 5, making it 5.
Step 4: 2 goes into 5 two times (2 × 2 = 4). Subtract 4 from 5 gives 1.
Step 5: As there are no more digits to bring down, we add a decimal point to the quotient and bring down a 0, making it 10.
Step 6: 2 goes into 10 five times (2 × 5 = 10). Subtract 10 from 10 gives 0. The division process ends here with a remainder of 0.
The answer for 45/2 as a decimal is 22.5.
