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 31, which 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 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.
31/100 in decimals can be written as 0.31. It is a terminating decimal, meaning it does not repeat the same digit infinitely.
To get 31/100 in decimal, we will use the division method. Here, as the numerator 31 is smaller than the denominator 100, we will directly get the decimal by placing 31 over 100 and performing the division:
Step 1: Identify the numerator and denominator because the numerator (31) will be taken as the dividend and the denominator (100) will be taken as the divisor.
Step 2: Using the division method, divide 31 by 100. Since 31 is smaller than 100, the quotient will start with 0.
Step 3: Add a decimal point in the quotient place and write 0.
Step 4: Multiply the remainder by 10, giving 310, and continue the division.
Step 5: 100 goes into 310 three times, which gives us 300. Subtracting gives a remainder of 10.
Step 6: Bring down another 0 to make 100, which is divided by 100 once, thus completing the division process as the remainder becomes 0. The answer for 31/100 as a decimal will be 0.31.
