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 8, which represents how many parts out of the whole. The denominator (number below) shows how many parts make the whole, here it is 64. 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 fraction part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
8/64 in decimal form can be simplified first to 1/8, which can be written as 0.125. It is a terminating decimal, meaning the digits do not repeat infinitely.
To get 8/64 in decimal form, we will use the division method. Here, as 8 is smaller than 64, we will take the help of the decimal method, which will give us 0.125. Let's see the step-by-step breakdown of the process:
Step 1: Simplify the fraction 8/64 to its simplest form, which is 1/8 by dividing both the numerator and the denominator by 8.
Step 2: Identify the numerator and denominator because the numerator (1) will be taken as the dividend and the denominator (8) will be taken as the divisor.
Step 3: As 1 is smaller than 8, it can't be divided; here, we will use decimals. We will add 0 to the dividend, making 1 as 10 and add a decimal point in the quotient place.
Step 4: Now that it is 10, we can divide it by 8. Let's see how many times 8 fits into 10.
Step 5: 8 goes into 10 once, so we write 1 in the quotient place and subtract 8 from 10, which gives 2.
Step 6: Bring down a 0 in the dividend place to make it 20, then divide by 8. 8 goes into 20 twice, so write 2 in the quotient.
Step 7: Subtract 16 (8×2) from 20 to get 4, bring down another 0 to make it 40. 8 goes into 40 five times, so write 5 in the quotient. The process ends here as the remainder becomes 0, confirming it is a terminating decimal.
The answer for 8/64 as a decimal is 0.125.
