11/4 + (3/10 x 4/15) =

11/4+(3/10x4/15)=11/4+2/25
=275/100+8/100
=283/100
=2 83/100

[tex] \frac{11}{4} + ( \frac{3}{10} \times \frac{4}{15} ) \\ = \frac{11}{4} + \frac{12}{150} \\ = diperkecil \: dulu \frac{12}{150} = \frac{4}{50} = \frac{2}{25} \\ jd \: \frac{11}{4} + \frac{2}{25} \\ = \frac{275}{100} + \frac{8}{100} \\ = \frac{283}{100} = 2\frac{83}{100} \\ maaf \: kalau \: salah:) \: semoga \: membantu:)[/tex]
