Mary is making chocolate chip cookies. The recipe calls for 18 cup of almonds for every 3/4 cup of chocolate chips if Louis uses 3 cups of chocolate chips, how many cups of almonds will he need round to the nearest tenth
To find the amount of almonds Louis will need, we need to set up a proportion based on the ratio given in the recipe.
The ratio of almonds to chocolate chips is 18:0.75
Let x be the amount of almonds needed. Since Louis is using 3 cups of chocolate chips, we can set up the proportion:
18/0.75 = x/3
Cross multiplying, we get:
0.75 * x = 18 * 3
0.75 * x = 54
Dividing both sides by 0.75, we get:
x = 54 / 0.75
x = 72
Therefore, Louis will need 72 cups of almonds.
