x = 5.y.z so 5.10.12 = 600
Multiply 0.1 by 400 to get 40. This is how you find 10% of 400 without using proportion.
1600 10% is equal to 0.1 and 1/10. You can either multiply by these numbers, or divide by 10 to find that 10% of 4000 is 400. 4000 - 400 = 1600

y = -5
y = 8
40 x 10 = 400
y varies directly with x means y = kx, where k is the constant of the variation. When x = 2.5 and y = 5, we have y = kx 5 = 2.5k k = 2 When x = 10, y = kx y = (2)(10) y = 20

y = kx: 10 = 37k so k = 10/37 and y = 10x/37
1 centimetre = 10 millimetres so 400 cm = 400*10 = 4000 mm. Simple!
