The number before the decimal point remains the same. How many digits are there after the decimal point? If there is a digit, divide it by 10, and then divide it.

For example, if 4.6=4*(6/ 10) 6/ 10 is divided by about 3/5, then the band score of 4.6 is 4 3/5.

If there are two digits after the decimal point, divide the digits after the decimal point by 100, and then subtract the points. And so on.

For example: 6.75=6*(75/ 100), then the band score of 6.75 is 6 3/4.
