The smallest fraction will have the lowest value number as the numerator and the highest value number as the denominator. The smallest value number that can be formed from 7,8,9, is 7 The largest value number is either 98 if the numbers can be used once only or 987 if repeated numbers are permitted or even 999. The possibilities are thus 7/98 or 7/987 or 7/999.
the difference in value. Ex) 7-3=4
The positional place values of digits in negative numbers are in ascending order from least to greatest as for example in the number -987 the least value digit is 9 and the greatest value digit is 7 because -900 < -80 < -7 The positional place values of digits in positive numbers are in descending order from greatest to least as for example in the number 987 the least value digit is 7 and the greatest value digit is 9 because 900 > 80 > 7
You can find the range of any set of numbers by subtracting the smallest value from the largest value, eg. in the set 1, 3, 5, 6, 7, 8 the range would be 8-1, or 7.
