as ur request. semoga membantu~~

2a)
[tex] \frac{x}{4}= \frac{5}{12} \\ 12\times x = 5 \times 4 \\ 12x=20 \\ x= \frac{20}{12} \\ x=1,667[/tex]

2b)
[tex] \frac{x}{9} = \frac{12}{8} \\ \frac{x}{9}= \frac{3}{2} \\ 2 \times x=3\times9 \\ 2x=27 \\ x= \frac{27}{2} \\ x= 13,5[/tex]

2c)
[tex] \frac{15}{y+4} = \frac{20}{16} \\ \frac{15}{y+4} = \frac{5}{4} \\ (y+4)\times5=15\times4 \\ 5y+20=60 \\ 5y=60-20 \\ 5y=40 \\ y= \frac{40}{5} \\ y=8[/tex]

2d)
[tex] \frac{y-3}{6} = \frac{21}{14} \\ \frac{y-3}{6}= \frac{3}{2} \\ (y-3)\times2=3\times6 \\ 2y-6=18 \\ 2y=18+6 \\ 2y=24 \\ y= \frac{24}{2} \\ y=12[/tex]
