3:5
3+5=8
82÷8=10.25
3(10.25):5(10.25)
30.75:51.25
the answer is 30.75:51.25
Complementary angles add up to 90 degrees
7:8....added = 15
7/15 * 90 = 630/15 = 42 <== one angle is 42 degrees
8/15 * 90 = 720/15 = 48 <== other angle is 48 degrees
You have to subtract 5/4 by 2/3 but in order to do that you must find a common denominator or least common multiple so the least common denominator of 4 and 3 is 12 so you have to multiply 4 by 3 and three by 4 to make both denominators 12 but you have to do the same thing on the top as you did the bottom so:
5/4*3= 15/12 and 2/3*4=8/12
Then 15/12-8/12 is 7/12 so Jim has to run 7/12 more
