Answer 2

Jawaban:

Penyelesaian :

[tex] \sf 2 \frac{1}{3} \times 5\% + 0,45[/tex]

[tex] \sf = \frac{7}{3} \times \frac{5}{100} + \frac{45}{100} [/tex]

[tex] \sf = \frac{7}{3} \times \frac{1}{20} + \frac{9}{20} [/tex]

[tex] \sf = \frac{7 \: \times \: 1}{3 \: \times \: 20} + \frac{9}{20} [/tex]

[tex] \sf = \frac{7}{60} + \frac{9}{20} [/tex]

[tex] \sf = \frac{7}{60} + \frac{(9 \times 3)}{60} [/tex]

[tex] \sf = \frac{7}{60 } + \frac{27}{60} [/tex]

[tex] \sf = \frac{34 \: : \: 2}{60 \: : \: 2} [/tex]

[tex] \sf = \frac{17}{30} [/tex]
