For the first one
3:5=g:65
3/5=g/65
3×65=5g
g=195/5
g=39
Follow the same procedure for the rest
Find the value of the variable in each proportion.
a) 3:5 = g:65
b) h:8 = 56:64
c) 16:m = 20:35
d) 36:8 = 81:f

get 1 on the same side as your unknown variable by multiplying or dividing both sides
eg:
3 / 5 = g / 65
multiply both sides by 65
3 * 65 / 5 = g * 65 /65 = g
3 *13 = g
eg:
3 / 5 = g / 65
multiply both sides by 65
3 * 65 / 5 = g * 65 /65 = g
3 *13 = g
