What is 9/5 as a decimal?
A decimal number can be defined as a number whose whole number part and the fractional part are separated by a decimal point.
Answer: 9/5 as a decimal is 1.8.
Let's look into the two methods to write 9/5 as a decimal.
Explanation:
Method 1: Writing 9/5 as a decimal using the division method.
To convert any fraction to decimal form, we just need to divide its numerator by denominator.
Here, the fraction is 9/5 which means we need to perform 9 ÷ 5.
This gives the answer as 1.8. So, 9/5 as a decimal is 1.8.
Method 2: Writing 9/5 as a decimal by converting the denominator to powers of 10.
Step 1: Find a number that we can multiply by the denominator of the fraction to make it 10 or 100 or 1000 and so on.
Step 2: Multiply both numerator and denominator by that number to convert it into an equivalent fraction.
Step 3: Then write down just the numerator, putting the decimal point in the correct place, that is, one space towards the left starting from the right-hand side for every zero in the denominator.
9/5 = (9 × 2) / (5 × 2) = 18/10 = 1.8
Irrespective of the methods used, the answer to 9/5 as a decimal will always remain the same.
