To convert the mixed number 4 5 into a decimal, we first need to understand that it consists of a whole number and a fraction. In this case, the number is 4 and the fraction is 5. Since 5 is typically not a fraction but can be understood as ‘5 over 1’, the conversion process involves taking the 4 and putting it in the whole number section, while converting 5 into a decimal.
First, we convert the fraction 5 into a decimal by recognizing that there’s no need for further conversion; it directly translates to 5.00 since there are no additional fractional parts. Therefore, the mixed number 4 5 can be represented in decimal form as 4 + 5 = 9.0.
Thus, 4 5 in decimal notation is 9.0.
