Ethan had 19 cookies. After giving away 1 cookie to his neighbor, he had two times as many cookies as Louisa. How many cookies did Louisa have?
19 -1 = 18
18 = 2L
Solve for L
After giving away 1 cookie to his neighbor, he had 19 - 1 = 18 cookies
He had two times as many cookies as Louisa.
18 = 2 ∙ Louisa´s cookies
Louisa have 18 / 2 = 9 cookies
To find out how many cookies Louisa had, we can follow these steps:
Step 1: Start with the number of cookies Ethan had, which is 19.
Step 2: Subtract the number of cookies Ethan gave away, which is 1.
Ethan's cookies after giving away 1 = 19 - 1 = 18.
Step 3: It is given that after giving away 1 cookie, Ethan had two times as many cookies as Louisa. So we can set up an equation using this information:
Ethan's cookies after giving away 1 = 2 * Louisa's cookies
18 = 2 * Louisa's cookies
Step 4: Solve the equation for Louisa's cookies:
Louisa's cookies = 18 / 2 = 9
Therefore, Louisa had 9 cookies.
