75 + 45

First let's find the greatest common factor.
75: 1, 3, 5, 15, 25, 75
45: 1, 3, 5, 9, 15, 45
Their GCF is 15.

To get 75, you multiply 15 by 5.
To get 45, you multiply 15 by 3.

Therefore, 15(5 + 3) = 75 + 45.

B. 15(5 + 3)

The length of a bridge is 140 m. The length of each of Robert's paces is 55 cm.

Sindrei [870]

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.
