7. B. 3,91 km
8. C. 13/24
9. C
10. D. 9/10
11. C. 11
12. D. 2,075
Penjelasan dengan langkah-langkah:
7. 2,36 + 1 11/20 = 2,36 + 1 55/100
= 2,36 + 1,55
= 3,91 km
8. 11/12 – 3/8 = 22/24 – 9/24
= 13/24
9. C. 5/6 – 1/4 = 10/12 – 3/12 = 7/12
1/2 = 6/12, maka 7/12 > 6/12
10. p + 4/5 = 1 7/10
p = 1 7/10 – 4/5
= 17/10 – 8/10
= 9/10
11. 5 1/5 – 19/4 = 26/5 – 19/4
= 104/20 – 95/20
= 9/20
a = 9, b = 20
b – a = 20 – 9 = 11
12. 4 5/8 – 2,55 = 4,625 – 2,550
= 2,075
