To arrange the masses of the fish in ascending order, we need to list them from the smallest to the largest value.
Given the masses:
2.1 kg
1.9 kg
2.3 kg
1.7 kg
Let's compare each mass:
1.7 kg is the smallest.
Next is 1.9 kg.
Then we have 2.1 kg.
Lastly, 2.3 kg is the largest.
So, the masses of the fish in ascending order are: 1.7 kg, 1.9 kg, 2.1 kg, 2.3 kg.
When arranging numbers in ascending order, always start with the smallest value and move towards the largest value. This method helps in organizing data systematically for better clarity and understanding.
