Are the lines in the diagram perpendicular, parallel, skew, or none of these?

l and m: neither
l and m intersect, but are not perpendicular. 

l and n: skew
l and n are not parallel, but they do not intersect because they are not on the same plane. 

m and n: perpendicular.
m and n intersect at a right angle

13/20

Step-by-step explanation: To write 0.65 as a fraction, think of 0.65 sixty-five hundredths which can be written as the fraction 65/100.Notice however that 65/100 is not in lowest terms so we need to divide the numerator and denominator by the greatest common factor of 65 and 100 which is 5 and we will get the equivalent fraction 13/20.

Therefore, 0.65 can be written as the fraction 13/20.
