It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part of the whole. It has two parts: the numerator (number on the top) here, 42 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 100. A decimal is a way to represent a number that is not whole, using a (.) or a decimal to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
42/100 in decimals can be written as 0.42. It is a terminating decimal, meaning it does not repeat infinitely.
To convert 42/100 to a decimal, we can simply divide the numerator by the denominator. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (42) will be taken as the dividend and the denominator (100) will be taken as the divisor.
Step 2: Divide 42 by 100. We will use the decimal method to perform the division.
Step 3: Since 42 is smaller than 100, the division will result in a value less than 1. Therefore, we place a decimal point in the quotient and add zeros to the dividend as needed.
Step 4: 42 divided by 100 gives you 0.42. Since there is no remainder, the division process ends here.
The answer for 42/100 as a decimal is 0.42.
