Hi! Here is a hint. Since there were an equal amount bought for both flowers, therefore, their difference in the number of stalks remained the same, which is 56. Refer to the image below for the solution.

19 905. The first value of 9 is 9 000. The second value of 9 is 900. The difference: 9000 – 900 = 8100

Hi, you may also easily see that each unshaded part is ¼, so ¾ is unshaded, and hence ¼ shaded.

Look at the 3 white portions; they made up of 4 units each. Total units = 16. Leaving black = 4 units. Therefore 4/16=1/4 (simplest form)
