0.4 cup

0.8 cup

18.0 cups

0.5 cup

Answer 1

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

Let's set up a proportion to solve for x, the number of cups of almonds Luis will need:

18 cups / 34 cups = x cups / 3 cups

Cross multiplying, we get:

18 cups * 3 cups = 34 cups * x cups

54 cups = 34x

Dividing both sides by 34, we get:

x = 54 cups / 34

x ≈ 1.6 cups

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

Lenny is making his own laundry soap. The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. If Lenny uses 7 cups of soap flakes, how many cups of borax and washing soda combined does he need?(1 point)

Answer 5

To find out how many cups of borax and washing soda Lenny will need, we need to calculate the total number of parts for borax and washing soda combined and then convert it to cups.

In the given recipe, the ratio is 2 parts borax + 2 parts washing soda + 1 part soap flakes.

This means that the total number of parts is 2 + 2 + 1 = 5.

To find out the amount of borax and washing soda combined, we need to find out what fraction each part represents out of the total number of parts.

For borax and washing soda combined, it will be (2/5) * total amount = (2/5) * 7 cups.

Calculating:
(2/5) * 7 = 14/5 ≈ 2.8 cups.

So, Lenny will need approximately 2.8 cups of borax and washing soda combined. Rounded to the nearest whole number, the answer is 3 cups.

Therefore, the correct answer is: 3 cups.
