Tolong dong gimana caranya??

1.
[tex] \frac{18}{5} + \frac{25}{100} \\ = \frac{18}{5} + \frac{1}{4} \\ = \frac{72}{20} + \frac{5}{20} \\ = \frac{79}{20} [/tex]
2.
[tex] \frac{23}{4} + \frac{20}{100} \\ = \frac{23}{4} + \frac{1}{5} \\ = \frac{115}{20} + \frac{4}{20} \\ = \frac{119}{20} [/tex]

3.3/5 = 18/5
25% = 25/100
18/5 + 25/100 = 72/20 + 5/20 = 77/20 = 3.17/20 atau 385% atau 3,85

5.3/4 = 23/4
20 % = 20/100
23/4 + 20/100 = 115/20 + 4/20 = 119/20 = 5.19/20 atau 595% atau 5,95

7.1/5 = 36/5
50% = 50/100
36/5 + 50/100 = 72/10 + 5/10 = 77/10 = 7.7/10 atau 770% atau 7,7
