It takes a cup of flour to make 100 cookies. How many cups of flour will it take to make 225 cookies?
1/100 = x/225 Would it be like this?
1 / 100 = x / 225
1 * 225 = x * 100
225 = 100 x Divide both sides by 100
225 / 100 = x
x = 2.25
Or simply :
225 / 100 = 2.25
Yes, you're on the right track! To determine the number of cups of flour needed to make 225 cookies, you can set up a proportion equation using the relationship between the number of cookies and the amount of flour.
The proportion equation can be set up as follows:
1/100 = x/225
Here, x represents the number of cups of flour needed to make 225 cookies.
To solve this equation for x, you can cross-multiply and then solve for x.
Cross-multiplying gives:
225 * 1 = 100 * x
225 = 100x
To isolate x, you can divide both sides of the equation by 100:
225/100 = x
2.25 = x
So, it will take approximately 2.25 cups of flour to make 225 cookies.
