2/4+1 3/5-4/10=plisss...buat jalannya y..

=
[tex] = \frac{2}{4} + 1 \frac{3}{5} - \frac{4}{10} \\ = \frac{2}{4} + \frac{8}{5} - \frac{4}{10} \\ = \frac{10}{20} + \frac{32}{20} - \frac{8}{20} \\ = \frac{10 + 32 - 8}{20} \\ = \frac{34}{20} \\ = \frac{17}{10} [/tex]

2/4 + 1 3/5 - 4/10=
2/4 + 8/5 - 4/10 =
10/20 + 32/20 - 8/10 =
34/20 =
1 14/20 =
1 7/10
