A decimal number can be defined as a number whose whole number part and the fractional part is separated by a decimal point.
Let's look into the two methods to write 9/16 as a decimal.
To convert any fraction to decimal form, we just need to divide its numerator by denominator.
Here, the fraction is 9/16 which means we need to perform 9 ÷ 16
This gives the answer as 0.5625. So, 9/16 as a decimal is 0.5625
Step 1: Find a number such 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 it's an equivalent fraction.
Step 3: Then write down just the numerator, putting the decimal point in the correct place, that is, one space from the right-hand side for every zero in the denominator.
9/16 = (9 × 625) / (16 × 625) = 5625/10000 = 0.5625
Irrespective of the methods used, the answer to 9/16 as a decimal will always remain the same.
