1) Ordering the numbers from least to greatest
135%=1.35, 13.5, 7.4
2) Ordering :
60%, 0.5, 3/10, 10%
6%=0.6
3/10 = 0.3
10%=0.1
3)
5a + 2x + 8ab +9b +12ab +7b +3x +10a +4ab
5a, 10a
2x, 3x
9b, 7b
8ab, 12ab
4)
-8 (2b +3) =-16b-24
b). -4 (4+3p) = -16 -12p
5)
Distributive
7(5n-8) + 6(4+6n) = 35n -56 +24+24n
Combining like terms
7(5n-8) + 6(4+6n) = 59n -32
