First of all, to simplify a number/fraction, you must find a common multiple.
Both 12 and 42 is divisible by 6

=

since 6 goes into 12, two times and goes into 42, 7 times. The answer is

when simplified.
Answer: same. ( 6 degree )
Step-by-step explanation:
According to the question, An angle that measures 6° is drawn on a piece of paper. As you are looking at the angle through a×6 magnifying glass, which means it magnifies by a factor of 6 indeed. The length and the width of the shape may magnify by factor of 6, but the degree measure of the angle will remain the same.
Even if it is magnified by a factor of 100, the measure of the angle you see on the paper when you look through the magnifying glass will remain the same.
