Radians as multiples of pi?

I need help with this question: How do I convert 80 degrees to radians and express the result as a multiple of pi? I believe that 80 degrees is approximately 1.3964 radians, but I'm unsure how to express it in terms of pi. Can someone guide me through the process?

Don’t use your calculator. Multiply degrees by pi/180 to convert to radians, so

80 degrees = 80pi/180 radians, now just reduce the fraction to lowest terms.

Eww no don’t do that. Usually we don’t look at radians in decimals, but fractions.

80 degrees = 80pi/180 = 4pi/9 Radians

pi radians is 180 degrees.

80 degrees is (80/180)(pi) = (4/9)(pi)
