Answer 2

Jawaban:

Penyelesaian :

[tex] \sf 3 \frac{3}{4} + 1,25 - 1 \frac{3}{5} [/tex]

[tex] \sf = \frac{15}{4} + \frac{125}{100} - \frac{8}{5} [/tex]

[tex] \sf = \frac{15}{4} + \frac{ { \cancel{125}}^{ \: \: 5} }{ { \cancel{100}}^{ \: \: 4} } - \frac{8}{5} [/tex]

[tex] \sf = \frac{15}{4} + \frac{5}{4} - \frac{8}{5} [/tex]

[tex] \sf = \frac{15 \times 5}{20} + \frac{5 \times 5}{20} - \frac{8 \times 4}{20} [/tex]

[tex] \sf = \frac{75}{20} + \frac{25}{20} - \frac{32}{20} [/tex]

[tex] \sf = \frac{100}{20} - \frac{32}{20} [/tex]

[tex] \sf = \frac{68}{20} [/tex]

[tex] \sf = \frac{17}{5} [/tex]

[tex] \sf = 3 \frac{2}{5} [/tex]
