$r = 9$ $r = 9$

Cross multiply:

$\frac{5 r}{6} = \frac{15}{2}$ $(5r)/6 = 15/2$

$5 r \times 2 = 15 \times 6$ $5r xx 2 = 15 xx 6$

$10 r = 90$ $10r = 90$

$r = \frac{90}{10}$ $r=90/10$

$r = 9$ $r = 9$

Checking the answer:

$\frac{5 (9)}{6} = \frac{15}{2}$ $(5(9))/6 = 15/2$

$\frac{45}{6} = \frac{15}{2}$ $45/6 = 15/2$

$\frac{15}{2} = \frac{15}{2}$ $15/2 = 15/2$ ---> Right!
