It is a simple question on decimal conversion. Firstly, we have to learn fractions and decimals. A fraction represents a part from the whole. It has two parts: numerator (the number on the top) and denominator (the number below). The numerator represents how many parts out of the whole, and the denominator shows how many parts make the whole. A mixed number consists of a whole number and a fraction. A decimal is a way to represent numbers that are not whole, using 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.
4 5/12 in decimals can be written as 4.41666... It is a recurring decimal, meaning the fractional part will repeat the same digit infinitely.
To convert 4 5/12 to a decimal, we will first convert the fraction 5/12 to a decimal and then add it to the whole number 4.
Step 1: Convert the fraction 5/12 to a decimal using division.
Step 2: The numerator (5) will be the dividend, and the denominator (12) will be the divisor.
Step 3: Perform the division 5 ÷ 12. Since 5 is smaller than 12, we add a decimal point and zeros to the dividend.
Step 4: 12 goes into 50 four times (12 × 4 = 48). Write 4 in the quotient place and subtract 48 from 50 to get 2.
Step 5: Bring down a 0, making it 20, and divide by 12 to get 1 (12 × 1 = 12). Subtract 12 from 20 to get 8.
Step 6: Bring down another 0 to make 80, and divide by 12 to get 6 (12 × 6 = 72). Subtract 72 from 80 to get 8.
Step 7: Continue this process as the remainder repeats, showing the decimal is recurring.
Finally, the decimal for 5/12 is approximately 0.41666..., and adding this to the whole number 4 gives 4.41666....
