IF the central angle is in degrees then the
arc length = (12 / 360) * circumference
arc length = (1 / 30) * 2 * PI * 30
arc length = 2 * PI inches
arc length = <span> <span> <span> 6.28 inches

Subtract the fractions and simplify the answer 7 8/9-5 3/5
weeeeeb [17]
One way in which to do this problem would involve subtracting 5 from 7 (result:  2) and then subtracting 3/5 from 8/9.
To subtract 3/5 from 8/9, you'd need to find the lowest common denominator (LCD) of 3/5 and 8/9, convert both fractions to have this LCD, and then subtract.

The LCD is (5)(9)=45.  Then 8/9 and 3/5 become 40/45 and 27/45.

Subtracting 27/45 from 40/45 results in the fraction 13/45.
Then the full solution is  2 13/45.

You could also do this problem by converting  7 8/9    and   5 3/5 into improper fractions:

71/9 - 28/5.  Again, the LCD is 45.  Can you rewrite both fractions with 45 as the common denominator and then perform the subtraction?
