12/40 as a decimal
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, 12 represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 40. A decimal is a way to represent a number that is not whole, using a (.) 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.
What is 12/40 as a decimal?
Answer
12/40 in decimals can be written as 0.3. It is a terminating decimal, meaning it does not repeat.
Explanation
To convert 12/40 to a decimal, we will use the division method. Here, as 12 is smaller than 40, we will divide directly.
Step 1: Identify the numerator and denominator because the numerator (12) will be taken as the dividend and the denominator (40) as the divisor.
Step 2: Divide 12 by 40. Since 12 is smaller than 40, the initial quotient is 0.
Step 3: Add a decimal point and a zero to the dividend, making it 120.
Step 4: Determine how many times 40 goes into 120. The closest is 3 times (since 40 × 3 = 120).
Step 5: Subtract 120 from 120, which gives 0, indicating the division is complete.
The answer for 12/40 as a decimal will be 0.3.
