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, 45, 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 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.
45/64 in decimals can be written as 0.703125. It is a terminating decimal.
To get 45/64 in decimal, we will use the division method. Here, 45 is smaller than 64, so we will take the help of the decimal method, which will give us 0.703125. Let's see the step-by-step breakdown of the process:
Step 1: Identify the numerator and denominator because the numerator (45) will be taken as the dividend and the denominator (64) will be taken as the divisor.
Step 2: As 45 is smaller than 64, it can't be divided. Here we will take the help of decimals. We will add 0 to the dividend, which will make 45 into 450, and add a decimal point in the quotient place.
Step 3: Now that it is 450, we can divide it by 64. Let's see how many times 64 fits into 450.
Step 4: 64 is multiplied by 7 to get 448, which is the closest multiple to 450 without exceeding it. We will write 7 in the quotient place and subtract 448 from 450, giving 2.
Step 5: Bring down another 0 in the dividend place, making it 20, and then repeat the division process.
Step 6: Continue the division until no remainder is left. This process yields the decimal 0.703125.
The answer for 45/64 as a decimal will be 0.703125.
