Converting Fractions to Decimal

To convert fractions to decimals, you need to divide the numerator (the top number) by the denominator (the bottom number). Let's convert the given fractions to decimals one by one:

1. 4 2/5: To convert 4 2/5 to a decimal, we first need to convert the mixed number to an improper fraction. Multiply the whole number (4) by the denominator (5) and add the numerator (2) to get the new numerator. The denominator remains the same. - 4 2/5 = (4 * 5 + 2) / 5 = 22/5 Now, divide the numerator (22) by the denominator (5) to get the decimal value. - 22 ÷ 5 = 4.4 Therefore, 4 2/5 is equal to 4.4 as a decimal.

2. 4 2/3: Similarly, convert 4 2/3 to an improper fraction. - 4 2/3 = (4 * 3 + 2) / 3 = 14/3 Divide the numerator (14) by the denominator (3) to get the decimal value. - 14 ÷ 3 ≈ 4.6667 (rounded to four decimal places) Therefore, 4 2/3 is approximately equal to 4.6667 as a decimal.

3. 9 1/5: Convert 9 1/5 to an improper fraction. - 9 1/5 = (9 * 5 + 1) / 5 = 46/5 Divide the numerator (46) by the denominator (5) to get the decimal value. - 46 ÷ 5 = 9.2 Therefore, 9 1/5 is equal to 9.2 as a decimal.

4. -3 1/4: Convert -3 1/4 to an improper fraction. - -3 1/4 = (-3 * 4 + 1) / 4 = -11/4 Divide the numerator (-11) by the denominator (4) to get the decimal value. - -11 ÷ 4 = -2.75 Therefore, -3 1/4 is equal to -2.75 as a decimal.

I hope this explanation helps! Let me know if you have any further questions.
