jika n=4/5+1.75-1 1/8,nilai n=

[tex] \frac{4}{5} + 1.75 - 1 \ \frac{1}{8} \\ \frac{4}{5} + \frac{175}{100} - \frac{9}{8} \\ \frac{4}{5} + \frac{7}{4} - \frac{9}{8} \\ \frac{32}{40} + \frac{70}{40} - \frac{45}{40} \\ \frac{57}{40} \\ 1 \frac{17}{40} [/tex]

4/5+1.75-1 1/8=4/5+175/100
9/8=4/5+7/4-9/8=32/40+
70/40-45/40=57/40=
1 17/40
maaf kalau salah
