Question

Instead of having 1.5 times as many pink flowers as white flowers, Molly has decided to plant a garden with twice as many pink flowers as white flowers per row. If she plants 3 rows, with 4, 6, and 8 pink flowers, how can you find the number of white flowers in each of those rows?

Answer 1

Suppose the number of white flowers is x.
The number of pink flowers will be 2x
Given that she planted 3 rows of 4,6 and 8 flowers, then number of white flowers in each row will be as follows:
1 st row.
2x=4
hence
x=4/2
x=2 flowers

2nd row
2x=6
x=6/3
hence
x=3 flowers

3rd row
2x=8
hence
x=8/2
x=4 flowers

Answer 2

Answer: To find the number of white flowers, use the constant of proportionality and the number of pink flowers per row. If Molly plants 4, 6, and 8 pink flowers in 3 rows, she has to plant 2, 3, and 4 white flowers in those rows, so there are twice as many pink flowers as white.                MIDDLESCHOOLMATH
