15/8 = 1.87
There are two parts to the decimal number.
Integer part is 1 and fractional part is 87
Make the fractional part just one digit by using rounding rules.
Rounding rule says that if the second digit in the fractional part is more than 5 and the first digit in the fractional aprt is less than 9, then add 1 to the first digit and remove second digit.
So, 15/8 rounded to the nearest tenth in decimal format is 1.9
1.9 in fractional format is 19/10.
Example: What is 15(8/9) rounded to the nearest half?
Given mixed number is 15(8/9)
Convert the mixed fraction to an improper fraction or fraction

= 143/9
Divide the numerator by the denominator of the fraction
143/9 = 15.88
Round this decimal number using rounding rules.
If the number to the right of the decimal point is 75 or above, then we add 1 to the left side of the decimal point and make the right side 0.
88 is greater than 75. So, add 1 to the integer part and make decimal part as zero.
15 (8/9) rounded to the nearest half is 16.
Example: Round 18(5/7) to the nearest whole number.
Given mixed number is 18(5/7)

= 131/7
Divide the numerator by the denominator the fraction
131/7 = 18.71
Round this decimal number using rounding rules.
If the number to the right of the decimal point is .5 or higher, then add 1 to the left of the decimal point.
0.71 is more than 0.5. So, add 1 to the left of the decimal point.
Therefore, 18(5/7) rounded to the nearest whole number is 19.
Example: What is 8 (3/4)" rounded to the nearest inch?

1. What is rounding of numbers?
Rounding means replacing the number with an approximate value that has a shorter representation. It is done to obtain a value that is easier to report and communicate than the original one. It is a process of making a number simpler but keeping its value close to the original value.
2. What is called rounding up and rounding down of numbers?
The process of rounding up of numbers means if the decimal form and followed by the numbers 5, 6, 7, 8, and 9 after the decimal point, then round the numbers up to the nearest whole number greater than the original. If a rounding number is followed by 0, 1, 2, 3, 4 then the round numbers down is called rounding down of numbers.
3. What are the rules in rounding decimal numbers?
The two important rules of rounding decimal numbers are rounding up and rounding down.
