irrational number
-2/3 + 3/4
-2/3 + 3/4 = 9/12 - 8/12
= 1/12
(-3/5) - (-7/10)
(-3/5) - (-7/10)
(-6/10) - (-7/10) = 1/10
-2/7(-5/8)
-2/7(-5/8) = 10/56
= 5/28
(-3/8) / (-9/16)
(-3/8) / -9/16 = (-3/8) x (-16/9+
48/72 = 2/3
Why are -2 and 2 called opposites?
They are the same distance from 0.
5/6 + (-7/8)
5/6 + (-7/8)
20/24 + (-21/24) = -1/24
3/8 - (-5/4)
3/8 - (-5/4)
3/8 + 10/8 = 13/8
= 1 5/8
