Penjelasan dengan langkah-langkah:
1. D
[tex] \sqrt{625} + \sqrt{196} = 25 + 14 = 39[/tex]
2. 133-15×13= 133-195= -62
3. A
[tex] \frac{17}{12} \div ( \frac{ - 5}{4} ) \times \frac{35}{34} = \frac{17}{12} \times ( \frac{ - 4}{5} ) \times \frac{35}{34} = \frac{ - 7}{6} = - 1 \frac{1}{6} [/tex]
4. 202-17= 185(A)
5. A
[tex] \frac{11 \times 125}{8 \times 125} = \frac{1375}{1000} = 1.375[/tex]
6. (7,82 - 6,32)×2,5= 1,5×2,5= 3,75 (C)
7. B
[tex] \frac{37}{7} + \frac{35}{4} - \frac{34}{5} = \frac{740}{140} + \frac{1225}{140} - \frac{952}{140} = \frac{1013}{140} = 7 \frac{33}{140} [/tex]
8. B
[tex] \frac{139}{5} - \frac{6}{7} = \frac{973}{35} - \frac{30}{35} = \frac{943}{35} = 26 \frac{33}{35} [/tex]
