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: numerator (number on the top) here, -4 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 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.
-4/25 in decimals can be written as -0.16. It is a terminating decimal, meaning it does not repeat infinitely.
To get -4/25 in decimal, we will use the division method. Here as -4 is smaller than 25, we will take help of the decimal method which will give us -0.16. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (-4) will be taken as the dividend and the denominator (25) will be taken as the divisor.
Step 2: As -4 is smaller than 25, it can't be divided. Here we will take the help of decimals. We will add 0 to the dividend, which will make -4 as -40 and add a decimal point in the quotient place.
Step 3: Now that it is -40, we can divide it by 25. Let's see how many times 25 makes -40.
Step 4: -40 is not a multiple of 25, so we will look for the nearest number that is 25 × 1 = 25. We will write -1 in the quotient place and subtract 25 from -40, which gives -15.
Step 5: Bring down another 0 in the dividend place and make -15 as -150 and then repeat the division process.
Step 6: -150 divided by 25 gives -6, and no remainder is left, making this a terminating decimal.
The answer for -4/25 as a decimal will be -0.16.
