= 5 3/8 + 4/5 x (7/4 + 75/100)
= 5 3/8 + 4/5 x 250/100
= 5 3/8 + 1000/500 (C)
= 5 3/8 + 2
= 43/8 + 2
= 59/8 = 7 3/8
2. Yang benar = 36 * 4 = 144
Yang tidak dijawab = 6 * 0 = 0 (B)
Yang Salah = 8 * -1 = -8
Total = 144 + 0 + -8 = 136
4. (-2) x (-2) : 2 = 2 :
=
5. Hasilnya C. 2/3
6. a + 4b = 36
a + 11b = 15
----------------- -
-7b = 21
b = -3
a + 4b = 36
a + 4.(-3) = 36
a + -12 = 36
a = 48
U25 = a + (n-1).b
= 48 + (24-1).-3
= 48 + 23 .-3
= 48 + -69
U25 = -21
