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 (the number on the top), here 91, represents how many parts out of the whole. The denominator (the 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 decimal point (.) 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.
91/100 in decimal can be written as 0.91. It is a terminating decimal, meaning it does not repeat infinitely.
To convert 91/100 to a decimal, we will use the division method. Since 91 is smaller than 100, we will directly proceed with decimal conversion, which will give us 0.91.
Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (91) will be taken as the dividend, and the denominator (100) will be taken as the divisor.
Step 2: Since 91 is smaller than 100, we can't divide it without using decimals. We will add a decimal point in the quotient place and consider it as 91.0.
Step 3: Divide 91 by 100. Since 91 is less than 100, the whole number part of the quotient is 0.
Step 4: Now, consider 910 and divide by 100. 100 goes into 910 a total of 9 times (9×100=900).
Step 5: Subtract 900 from 910 to get 10. Step 6: Bring down another 0 in the dividend place to make it 100, and divide by 100. This gives a quotient of 1.
Thus, 91/100 as a decimal is 0.91.
