I don't get this:
Arya makes cupcakes at a bakery. She needs 2 cups of sugar for every 3 cups of flour. She needs 5 cups of flour to make a day's worth of cupcakes.
How many cups of sugar will she need? (Round your answer to the nearest tenth.)
Can you please help?
You can use a proportion.
2/3 = x/5
Cross multiply and solve for x.
31/3
Of course! To solve this problem, we need to figure out the ratio of cups of sugar to cups of flour. In this case, Arya needs 2 cups of sugar for every 3 cups of flour.
Next, we need to determine how many cups of flour Arya needs to make a day's worth of cupcakes, which is given as 5 cups of flour.
To find out how many cups of sugar Arya needs, we can set up a proportion using the ratio we found earlier:
2 cups of sugar / 3 cups of flour = x cups of sugar / 5 cups of flour
We can cross-multiply and solve for "x", which represents the amount of sugar Arya needs:
2 cups of sugar * 5 cups of flour = 3 cups of flour * x cups of sugar
10 cups of sugar = 3x
Divide both sides by 3:
10 cups of sugar / 3 = x
Using a calculator, we can determine that the value of x is approximately 3.33 cups of sugar.
Therefore, Arya will need approximately 3.3 cups of sugar to make a day's worth of cupcakes.
