Selesaikan operasi hitung berikut ini!
Jawab:
1. 16 : 4 + 7 1/3 = 11 1/3
2. 36 x 1/4 x 25 = 225
3. 12 x 5 + 17 = 77
4. (75 x 3) – (15 : 1/3) = 180
5. (80 – 5) : (12 – 7) = 15
6. 45 + (42 : 6 : 3) + 25 = 91
7. (8x (4 x 6 : 3) + 25) = 89
8. (35 : 7 + 10) : (2 + 1) = 5
Penjelasan dengan langkah-langkah:
1. (16 : 4) + 71/3 = 4 + 7 1/3
= 4 + 22/3
= 4/1 + 22/3
= 12/3 + 22/3
= 34/3
= 11 1/3 (sebelas satu per tiga)
2. (36 x 1/4) x 25 = 9 x 25
= 225
3. (12 x 5) + 17 = 60 + 17
= 77
4. (75 x 3) – (15 : 1/3) = 225 – 45
= 180
5. (80 – 5) : (12 – 7) = 75 : 5
= 15
6. 45 + (42 : [6 : 3]) + 25 = 45 + (42 : 2) + 25
= 45 + 21 + 25
= 91
7. (8 x (4 x [6 : 3]) + 25 = (8 x (4x 2)) + 25
= (8 x 8) + 25
= 64 + 25
= 89
8. ([35 : 7] + 10) : (2 + 1) = (5 + 10) : 3
= 15 : 3
= 5
