75% = 0.75Therefore, 75% x 1600 = 0.75 x 1600 = 1200.
.3 X 1600 = 480
30% of $1600 = 30/100 x 1600/1 = 30/1 x 16/1 = $480
x X 12 = 1600 Divide both sides by '12' Hence #x = 1600/12 Cancel down by '4' x = 400/3 Divide by '3' x = 133.33333.... ( recurring to infinity~) in fractional form 133. 1/3
They are: 1600 = 1 x 1600 1600 = 2 x 800 1600 = 4 x 400 1600 = 5 x 320 1600 = 8 x 200 1600 = 10 x 160 1600 = 16 x 100 1600 = 20 x 80 1600 = 25 x 64 1600 = 32 x 50 1600 = 40 x 40
x * 1600 = 400 x = 400 / 1600 x = 1/4 x = 25% ■
1600 x 29 = 46400

35% = 0.35Therefore, 35% x 1600 = 0.35 x 1600 = 560.
The good thing about this type of conversion is that feet are made from inches. We know that 1 foot = 12 inches, therefore, 1600 feet x 12 inches/feet = 19200 inches.
75% = 0.75Therefore, 75% x 1600 = 0.75 x 1600 = 1200.
.3 X 1600 = 480
1600 x .008 = 12.8
1600 x 100 = 160000%
30% of $1600 = 30/100 x 1600/1 = 30/1 x 16/1 = $480
