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 = 40......so 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 = 20.....so 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 = 21.....so 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 = 30....so 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 = 14.....so 14 is 40% of 35....14 goes in the box
