3/10 of A= = 2/5 of C
6/10 of A = 6/15 of C
A -> 10 units, shaded A -> 6 units, unshaded A -> 4 unuts
C-> 15 units, shaded C -> 6 units, unshaded C -> 9 units
shaded B -> 12 units (total shaded)
80% of B -> 12 units, B -> 15 units, unshaded B -> 3 units

can u continue from here?

cheers.

Is it 10 + 15 + 15 - 12 = 28 (units that whole figure has)
Shaded: 6 + 6 = 12

Answer: 16/28

Is this correct?[/quote]yes... 4/7 in simplest form

cheers.

Find the equation of the line which passes through the origin and is parallet to AB.

Gradient of AB = (7-0)/(0-5) = -1. 4

equation of line parallel to AB and passing thru the origin is

y = -1.4x
