reverse sides
12s/19 = 7b/15
multiply by 19
12s = 7b 19*/15
divide by b
12s/b = 7*19/15
divide by 12
s/b = 7/12 *19/15
Ratio od s to b:
s/b = 133/180
12s/19 = 7b/15
multiply by 19
12s = 7b 19*/15
divide by b
12s/b = 7*19/15
divide by 12
s/b = 7/12 *19/15
Ratio od s to b:
s/b = 133/180

s/b=(7*19)/(15*12)
