There is a percent formula that can solve all of these...
is / of = % / 100

what percent is 32 out of 80...
% = x...because this is what we r looking for
is = 32
of = 80
now sub into the formula
32/80 = x/100
cross multiply because this is a proportion
(80)(x) = (32)(100)
80x = 3200
x = 3200/80
x = 40so 32 is 40% of 80

12 is 60% of what number...
is = 12
% = 60
of = x

sub
12/x = 60/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20so 12 is 60% of 20

what is 30% of 70
is = x
% = 30
of = 70

x / 70 = 30/100
(100)(x) = (30)(70)
100x = 2100
x = 2100/100
x = 21so 21 is 30% of 70

what is 40% of 75
is = x
% = 40
of = 75

x / 75 = 40/100
(100)(x) = (75)(40)
100x = 3000
x = 3000/100
x = 30so 30 is 40% of 75

the pic
what is 40% of 35
is = x
% = 40
of = 35

x/35 = 40/100
(100)(x) = (35)(40)
100x = 1400
x = 1400/100
x = 14so 14 is 40% of 3514 goes in the box

It's like discovering the answer to a puzzle. the purpose in solving an equation is to find the value or values of the variable that makes it a true statement. any value of the variable that makes the equation true is called a solution to the equation.
