Best friends Olivia and Sylvia both get a weekly allowance. Olivia’s and Sylvia’s allowances are in the ratio 2:3 . If Sylvia gets $21 one week, how much did Olivia get? Use a tape diagram to help organize your thinking.(1 point)
To solve this problem, we can use a tape diagram to represent the ratio of Olivia's and Sylvia's allowances.
Let's represent Olivia's allowance as 2 units and Sylvia's allowance as 3 units. Since Sylvia gets $21, we can set up the equation:
3 units = $21
To find the value of 1 unit, we divide both sides of the equation by 3:
1 unit = $21 ÷ 3
1 unit = $7
Now that we know the value of 1 unit, we can find Olivia's allowance by multiplying 2 units by the value of 1 unit:
Olivia's allowance = 2 units × $7
Olivia's allowance = $14
Therefore, Olivia gets $14.
