Answer:
1 hour = 60 minutes
20 minutes = 1/4 of 60 minutes, which means 60 minutes = 4/4
when you write ratios, the larger number goes first - 60 minutes out of 15 minutes = 4/1, so the ratio in simplest form is 4:1

Answer:
The most absolute error is 12
Step-by-step explanation:
The formula for absolute error is given by the following relation;
Absolute error, Δx = Value measured, x₀ - Exact (actual) value, x
Δx = x₀ - x
Since the actual count is between 77 and 89, the maximum absolute error will be where the actual value = 77 and the measured value = 89 and vice versa, giving an absolute error of 89 -77 = 12.
The most absolute error = 12.
