Answer 1

To compare the quantities of pink, purple, and white flowers, we can use ratios. In Nora's arrangement, the ratios would be 7:21 for pink flowers, 9:21 for purple flowers, 5:21 for white flowers, and 21:21 for the total quantity.

Step-by-step explanation:

To compare the quantities of pink, purple, and white flowers in Nora's arrangement using ratios, we can write the following:

a) To compare the quantity of pink flowers, we can write the ratio as 7:21, because there are 7 pink flowers out of a total of 7+9+5 = 21 flowers.

b) To compare the quantity of purple flowers, we can write the ratio as 9:21, because there are 9 purple flowers out of a total of 7+9+5 = 21 flowers.

c) To compare the quantity of white flowers, we can write the ratio as 5:21, because there are 5 white flowers out of a total of 7+9+5 = 21 flowers.

d) To compare the total quantity of flowers, we can write the ratio as 21:21, because there are a total of 21 flowers.
