Answer:
The first row has 4 pink flowers and 2 white flowers
The second row has 6 pink flowers and 3 white flowers
The third row has 8 pink flowers and 4 white flowers.
Explanation:
Based on the above question,
Molly has decided to plant a garden with twice as
many pink flowers as white flowers per row.
We can find the number of white flowers in each row by using the principle of ratio to solve this question.
Mathematically, what Molly planted is expressed as:
2 pink flowers : 1 white flower
Therefore for the three rows:
a. The first row is 4 pink flowers
Since, 2 pink flowers : 1 white flower
2 pink flowers = 1 white flower
4 pink flowers = designated as y
We cross multiply
2× y = 4 × 1
Divide both sides by 2
y = 4 ÷ 2
y = 2 white flowers.
Therefore, the first row that Molly planted 4 pink flowers has 2 white flowers.
b. The second row, Molly planted 6 pink flowers
Since, 2 pink flowers : 1 white flower
2 pink flowers = 1 white flower
6 pink flowers = designated as z
We cross multiply
2× z = 6 × 1
Divide both sides by 2
z = 6 ÷ 2
z = 3 white flowers.
Therefore, the second row that Molly planted 6 pink flowers has 3 white flowers.
c. The third row , Molly planted 8 pink flowers
Since, 2 pink flowers : 1 white flower
2 pink flowers = 1 white flower
8 pink flowers = designated as p
We cross multiply
2× p = 4 × 1
Divide both sides by 2
P = 8 ÷ 2
y = 4 white flowers.
Therefore, the third row that Molly planted 8 pink flowers has 4 white flowers.
Therefore, since Molly has decided to plant a garden with twice as
many pink flowers as white flowers per row,
The first row has 4 pink flowers and 2 white flowers
The second row has 6 pink flowers and 3 white flowers
The third row has 8 pink flowers and 4 white flowers.
