Answer 1

10 contoh soal bilangan bulat :
1) 2 + (-2 × 3)
= 2 + (-6)
= -4
2) 51 : (-3) + 12 × (-2)
= -17 + -24
= -41
3) 84 : 12 × (-7) + 55
= 7 × (-7) + 55
= -49 + 55
= 6
4) 72 : (-8) × (-1)
= -9 × (-1)
= 9
5) 16 + (-3) × 5 - 13
= 16 + (-15) - 13
= 1 - 13
= -12
6) 61 + (-15) × 4
= 61 + (-60)
= 1
7) 81 : (-9) + 3 × (-3)
= -9 + (-9)
= -18
8) 50 + (-14) × 4
= 50 + (-56)
= -6
9) 14 + 25 : (-5)
= 14 + (-5)
= 9
10) 24 × (-2) + 21 : 7 - (-4)
= -48 + 3 + 4
= -45 + 4
= -41

10 contoh soal pecahan
1) ⅓ + ¼
= 4/12 + 3/12
= 7/12
2) ⅜ + ¾ - ⅔
= 9/24 + 18/24 - 16/24
= 27/24 - 16/24
= 11/24
3) ⅞ - ⅔
= 21/24 - 16/24
= 5/24
4) 3½ - 2⅜ + 1¾
= 3 4/8 - 2 3/8 + 1 6/8
= 1⅛ + 1 6/8
= 2⅞
5) 5½ × 3
= 11/2 × 3
= 33/2
= 16½
6) 6½ : ⅓
= 6½ × 3
= 13/2 × 3
= 39/2
= 19½
7) 1½ + 2⅓ × 1¾
= 3/2 + 7/3 × 7/4
= 3/2 + 49/12
= 18/12 + 49/12
= 67/12
= 5 7/12
8) 1⅔ - 4½ : 7⅝
= 5/3 - 9/2 : 61/8
= 5/3 - 9/2 × 8/61
= 5/3 - 36/61
= 305/183 - 108/183
= 197/183
= 1 14/183
9) 1⅔ + 3½ - 5⅜
= 4 + 4/6 + 3/6 - 5⅜
= 4 7/6 - 5 3/8
= 31/6 - 43/8
= 124/24 - 129/24
= -5/24
10) 1⅔ + 3½ - 2⅝ × 1½ : 5¾
= 4 + 4/6 + 3/6 - 21/8 × 3/2 : 23/4
= 4 7/6 - 63/16 × 4/23
= 31/6 - 252/368
= 55384/1104 - 756/1104
= 54628/1104
= 49 532/1104
= 49 133/276
