Full Answer
0.47
To convert the fraction 15/32 to a decimal, we divide the numerator (15) by the denominator (32).
Using a calculator:
15 ÷ 32 = 0.46875
The question asks for the answer to be given to 2 decimal places. To do this, we look at the third decimal place.
The number is 0.46875.
The first decimal place is 4.
The second decimal place is 6.
The third decimal place is 8.
Since the third decimal place (8) is 5 or more, we round up the second decimal place.
So, the 6 becomes a 7.
The answer is 0.47.
