the percentage = 61/144 × 100 = 6100/144 = 42.3611111111 ≈ 42.36%
Approximately % of these cats weigh between 2.5 and 2.75 kg
percentage = 20/144 ×100 = 2000/144 = 13.8888888889 ≈ 13.90%
Approximately % of these cats weigh between 2.75 and 3.5kg.

Explanation:
The picture below is the histogram used .
The horizontal is the weight of the cat . The vertical is the number of cat. The cats have 47 female and 97 male . The total cats is 47 + 97 = 144.
Approximately % of these cats weigh less than 2.5kg
Cat that weighs less than 2.5 kg is the sum of the first bar and the second bar. The sum is 29 + 32 = 61
61 cat weighs less than 2.5 kg
the percentage = 61/144 × 100 = 6100/144 = 42.3611111111 ≈ 42.36
Approximately % of these cats weigh between 2.5 and 2.75 kg
cat that weigh between 2.5 and 2.75 is 20
percentage = 20/144 ×100 = 2000/144 = 13.8888888889 ≈ 13.90
Approximately % of these cats weigh between 2.75 and 3.5kg.
The number of cat that fall under this category is 27 + 12 + 15 = 54
percentage = 54/144 × 100 = 5400/144 = 37.5
