23f in verbal expression"twenty-three f".
20 = 2 x 2 x 5
15 = 3 x 5
common divisor (CD) of 20 and 15 is 5 so n should be 5 and each group has 4 boys and 3 girls.
If there are more than one CD, then there are more than one answer.
If they ask for the largest number of groups, greatest common divisor (GCD) will be the answer.
Answer:
2 rational number because it's negative it can't be natural and cuz it's fraction it can't be whole nor integers
Different examples above! hope this helps c:
