Answer:
255 steps
Step-by-step explanation:
They give us the length of the bridge and the length of each step of Robert, therefore we must divide these values to find the number of steps necessary, but first we must pass the distance of the bridge to centimeters:
140m * 100cm / 1m = 14000
Therefore the bridge would have a length of 14000 centimeters, we divide:
14000/55 = 254.54
Which means that Robert take at least 255 steps to fully walk the bridge.

Answer: 16%
Step-by-step explanation:
The total number of species of shark evaluated = 465
Number of sharks currently endangered or threatened = 74
Percent of sharks endangered = (Number of sharks / Total number of sharks evaluated) x 100%
= (74/465) x 100%
= 0.1591 x 100%
= 15.91%
Round 15.91% to the nearest whole percent = 16%
Thus, 16% of the total sharks evaluated are currently endangered or threatened.
