To find out how many cups of almonds Luis will need, we can set up a proportion:

18 cups of almonds / 34 cups of chocolate chips = X cups of almonds / 3 cups of chocolate chips

Cross-multiplying, we get:

18 cups * 3 cups of chocolate chips = 34 cups * X cups of almonds

54 cups of chocolate chips = 34 cups * X cups of almonds

Simplifying, we get:

54 cups = 34X

Dividing both sides by 34, we get:

X = 54 cups / 34

Simplifying, X is approximately 1.6 cups of almonds.

So, Luis will need approximately 1.6 cups of almonds. Rounding to the nearest tenth, the answer is 0.5 cup.

According to the recipe, Lenny needs 2 parts of borax, 2 parts of washing soda, and 1 part of soap flakes.

Since Lenny is using 7 cups of soap flakes, we can calculate the amounts of borax and washing soda needed.

Borax: 2 parts * 7 cups = 14 cups
Washing soda: 2 parts * 7 cups = 14 cups

Therefore, Lenny needs a combined total of 14 cups of borax and washing soda.

9 tsp

To solve this problem, we can set up a ratio using the given information:

2 tsp baking soda / 6 lbs of flour = X tsp baking soda / 9 lbs of flour

Cross-multiplying, we get:

2 tsp * 9 lbs of flour = 6 lbs of flour * X tsp baking soda

18 tsp = 6 lbs of flour * X tsp baking soda

Dividing both sides by 6 lbs of flour, we get:

X tsp baking soda = 18 tsp / 6 lbs of flour

Simplifying, we find that X is equal to 3 tsp baking soda.

Therefore, Lisa should add 3 tsp of baking soda to 9 lbs of flour.

To find out how many cups of almonds Luis will need, we can use the given ratio of almonds to chocolate chips. According to the recipe, for every 34 cup of chocolate chips, 18 cup of almonds are required.

So, to calculate the amount of almonds needed when Luis uses 3 cups of chocolate chips, we can set up a proportion:

18 cups of almonds / 34 cups of chocolate chips = X cups of almonds / 3 cups of chocolate chips

Cross-multiplying, we get:

18 cups of almonds * 3 cups of chocolate chips = 34 cups of chocolate chips * X cups of almonds

Simplifying further:

54 cups of almonds = 34 cups of chocolate chips * X cups of almonds

Dividing both sides of the equation by 34 cups of chocolate chips, we get:

54 cups of almonds / 34 cups of chocolate chips = X cups of almonds

Calculating the result:

X = 54/34 ≈ 1.588

Rounding to the nearest tenth, Luis will need approximately 1.6 cups of almonds.
