This is a simple question on decimal conversion. Firstly, we need to understand fractions and decimals. A fraction represents a part of a whole. It has two parts: the numerator (the number on the top), here 55 represents how many parts out of the whole we are considering. The denominator (the number below) shows how many parts make up 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 fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
55/64 as a decimal is approximately 0.859375. It is a terminating decimal, meaning it does not repeat infinitely.
To convert 55/64 into a decimal, we will use the division method. Since 55 is smaller than 64, we will use the decimal method to perform the division. Let's break down the steps of the process:
Step 1: Identify the numerator and denominator. The numerator (55) will be the dividend, and the denominator (64) will be the divisor.
Step 2: Since 55 is smaller than 64, we can't divide it directly, so we will introduce a decimal point in the quotient and add 0 to the dividend, making it 550.
Step 3: Now, divide 550 by 64. Determine how many times 64 can fit into 550.
Step 4: 64 goes into 550 eight times (64 × 8 = 512). Write 8 in the quotient, and subtract 512 from 550, leaving a remainder of 38.
Step 5: Bring down another 0 to make it 380, and repeat the division process.
Step 6: 64 goes into 380 five times (64 × 5 = 320). Write 5 in the quotient, and subtract 320 from 380, leaving a remainder of 60.
Step 7: Bring down another 0 to make it 600, and divide by 64.
Step 8: 64 goes into 600 nine times (64 × 9 = 576). Write 9 in the quotient, and subtract 576 from 600, leaving a remainder of 24.
Step 9: Bring down another 0 to make it 240, and divide by 64.
Step 10: 64 goes into 240 three times (64 × 3 = 192). Write 3 in the quotient, and subtract 192 from 240, leaving a remainder of 48.
Step 11: Bring down another 0 to make it 480, and divide by 64.
Step 12: 64 goes into 480 seven times (64 × 7 = 448). Write 7 in the quotient, and subtract 448 from 480, leaving a remainder of 32.
Step 13: Bring down another 0 to make it 320, and divide by 64.
Step 14: 64 goes into 320 five times (64 × 5 = 320). Write 5 in the quotient, and subtract 320 from 320, leaving a remainder of 0. Now, the division process ends as we have reached a remainder of 0.
The decimal representation of 55/64 is 0.859375.
