Shapes are black and white, and are circles or squares. The ratio of circles to squares is 2: 3. Of the circles, the ratio of black to white is 4: 5. Of the squares, the ratio of black to white is 5: 2 .

(a) What fraction of the shapes are black?

(b) Determine the ratio of black circles to white squares.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
