1 1/4 dikali 3/10 dibagi 9/14

[tex]1 \frac{1}{4} = \frac{5}{4} [/tex]
maka cara menghitungnya :
[tex] = (\frac{5}{4} \times \frac{3}{10} ) \div \frac{9}{14} \\ = \frac{15}{40} \div \frac{9}{14} \\ = \frac{15}{40} \times \frac{14}{9} \\ = \frac{210} {360} \\ disederhanakan \: menjadi \\ = \frac{7}{12} [/tex]

[tex] \frac{7}{12} jawabanya[/tex]
