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 18, represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 25. A decimal is a way to represent a number that is not whole, using a (.) or 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.
18/25 in decimals can be written as 0.72. It is a terminating decimal, meaning it does not repeat indefinitely.
To get 18/25 in decimal, we will use the division method. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because numerator (18) will be taken as the dividend and denominator (25) will be taken as the divisor.
Step 2: Since 18 is smaller than 25, we will add a decimal point to the quotient and add zeros to the dividend.
Step 3: Consider 180 (by adding a zero) and divide it by 25. Determine how many times 25 goes into 180.
Step 4: 25 goes into 180 seven times, as 25 × 7 = 175. Write 7 in the quotient and subtract 175 from 180 to get 5.
Step 5: Bring down another 0 in the dividend place to make it 50. Divide 50 by 25, which goes exactly 2 times.
Step 6: Write 2 in the quotient. Since there's no remainder left, this process ends here. The answer for 18/25 as a decimal is 0.72.
