Hello, can you me with my math homework?
7/16 - 5/12. difference
5/6 + 9/10.
10 1/5 + 5 6/11.
6 2/9 - 2 5/6.
if you have any advice on how to simplify these fractions, tell me! !

What is best way to getting answer for my exam is

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.

Iknow its nothing to do with education, but what type of thing should i wrote here? ? : ) its for mcdonald's btw.
