Which is not in the form of a ratio

b is the answer

Step-by-step explanation:

We're going to start with the first one

60m/1 HR  

The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2.  So it would be  120 : 2

The next one only has 1 number and that is 1

It is not a form of a ratio because you can't turn a one digit  number into a ratio. A ratio has two digits for each side for an example:

This can be turned  into a ratio /  19 to 8

This cannot be turned  into a ratio/ 8

So there you have it letter b is your answer.

step-by-step explanation:

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
