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 121, which represents how many parts out of the whole. The denominator (the number below) shows how many parts make the whole, here it is 200. 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.
121/200 in decimals can be written as 0.605. It is a terminating decimal, meaning it does not repeat infinitely.
To convert 121/200 into a decimal, we will use the division method. Since 121 is smaller than 200, the division will yield a decimal. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (121) will be taken as the dividend and the denominator (200) will be taken as the divisor.
Step 2: Divide 121 by 200. Since 121 is smaller than 200, the result will start with 0.
Step 3: Place a decimal point in the quotient and add a zero to the dividend, making it 1210. Now, divide 1210 by 200.
Step 4: 200 goes into 1210 exactly 6 times (200 × 6 = 1200). Write 6 in the quotient place. Subtract 1200 from 1210 to get a remainder of 10.
Step 5: Bring down another 0, making it 100. Divide 100 by 200, which goes 0 times.
Step 6: Bring down another 0, making it 1000. Divide 1000 by 200, which goes 5 times (200 × 5 = 1000). Write 5 in the quotient place. The division process ends here, as the remainder is 0.
Thus, the answer for 121/200 as a decimal is 0.605.
