To determine how many cups of borax and washing soda combined Lenny needs, we need to find the total number of parts in the recipe.
The recipe calls for:
- 2 parts borax
- 2 parts washing soda
- 1 part soap flakes
Therefore, there are a total of 2 + 2 + 1 = 5 parts in the recipe.
Since Lenny is using 7 cups of soap flakes, we can divide it by the number of parts in the recipe (5) to find the amount of each part.
Each part would be equal to 7/5 = 1.4 cups.
To find the amount of borax and washing soda combined, we multiply the number of parts (2 + 2) by the amount of each part (1.4 cups):
(2 + 2) * 1.4 = 4 * 1.4 = 5.6
So, Lenny needs a combined total of 5.6 cups of borax and washing soda.
The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes. Since Lenny is using 7 cups of soap flakes, we need to determine how many cups of borax and washing soda he needs.
To calculate the amount of borax and washing soda needed, we need to multiply the number of cups of soap flakes by the ratio of borax and washing soda to soap flakes.
Since the ratio is 2 parts borax to 1 part soap flakes, we can calculate the cups of borax needed by multiplying the number of cups of soap flakes by the ratio:
2 * 7 cups = 14 cups of borax.
Similarly, since the ratio is 2 parts washing soda to 1 part soap flakes, we can calculate the cups of washing soda needed by multiplying the number of cups of soap flakes by the ratio:
2 * 7 cups = 14 cups of washing soda.
Therefore, Lenny needs a total of 14 cups of borax and washing soda combined.
To calculate the amount of borax and washing soda needed, we need to determine the ratio of soap flakes to borax and washing soda in the recipe. The recipe states that we need 2 parts borax, 2 parts washing soda, and 1 part soap flakes.
Since Lenny is using 7 cups of soap flakes, we can set up the following equation:
2 parts borax = 7 cups soap flakes
To solve for the amount of borax, we can set up a proportion:
2 parts / 1 part = X cups / 7 cups
Cross multiplying, we get:
2 * 7 = X * 1
14 = X
Therefore, Lenny needs 14 cups of borax.
To find the amount of washing soda, we use the same proportion:
2 parts washing soda = 7 cups soap flakes
2 parts / 1 part = X cups / 7 cups
Cross multiplying, we get:
2 * 7 = X * 1
14 = X
Therefore, Lenny needs 14 cups of washing soda.
Now, to find the total amount of borax and washing soda combined, we add the quantities together:
14 cups (borax) + 14 cups (washing soda) = 28 cups.
Therefore, Lenny needs 28 cups of borax and washing soda combined.
