Luis is making chocolate chip cookies. The recipe calls for 18 cup of almonds for every 34 cup of chocolate chips. If Luis uses 3 cups of chocolate chips, how many cups of almonds will he need? Round to the nearest tenth
A: 18.0 cup
B: 0.4 cup
C: 0.8 cup
D: 0.5 cup
To find the ratio of almonds to chocolate chips, divide the number of cups of almonds by the number of cups of chocolate chips: 18/34 = 0.529.
To find the number of cups of almonds needed, multiply the number of cups of chocolate chips by the ratio: 0.529 * 3 = 1.587.
Rounding to the nearest tenth, Luis will need 1.6 cups of almonds.
Thus, the answer is not listed.
To find out how many cups of almonds Luis will need, we can set up a proportion using the ratio provided in the recipe.
The proportion can be set up as:
18 cup of almonds / 34 cup of chocolate chips = x cup of almonds / 3 cups of chocolate chips
To solve for x, we can cross-multiply and then solve for x:
18 cup of almonds * 3 cups of chocolate chips = 34 cup of chocolate chips * x cup of almonds
54 cup of almonds = 34x
To find x, we can divide both sides of the equation by 34:
54 cup of almonds / 34 = x
x ≈ 1.59 cups
To round to the nearest tenth, we can round 1.59 to 1.6 cups.
Therefore, Luis will need approximately 1.6 cups of almonds.
None of the answer choices provided match this result, so there seems to be an error.
To find out how many cups of almonds Luis will need, we can set up a proportion based on the ratio given in the recipe.
The ratio in the recipe is 18 cups of almonds for every 34 cups of chocolate chips.
Let x be the number of cups of almonds Luis will need.
We can set up the proportion as follows:
18 cups of almonds / 34 cups of chocolate chips = x cups of almonds / 3 cups of chocolate chips
Cross-multiplying the proportion, we get:
18 cups of almonds * 3 cups of chocolate chips = 34 cups of chocolate chips * x cups of almonds
54 cups of almonds = 34 cups of chocolate chips * x cups of almonds
Dividing both sides by 34 cups of chocolate chips, we get:
54 cups of almonds / 34 cups of chocolate chips = x cups of almonds
Simplifying the fraction, we get:
1.588 cups of almonds = x cups of almonds
Rounding to the nearest tenth, we find that Luis will need approximately 1.6 cups of almonds.
Therefore, the answer is not provided in the options.
