To find out how many cups of borax and washing soda combined Lenny needs, we need to calculate the total number of parts in the recipe.
The recipe calls for 2 parts borax, 2 parts washing soda, and 1 part soap flakes.
Since borax and washing soda have the same proportion, we can combine their parts together. So the total number of parts for borax and washing soda is 2 + 2 = 4 parts.
To find out how many cups of borax and washing soda combined Lenny needs, we need to divide the total number of cups of soap flakes by the total number of parts.
So, 7 cups / 4 parts = 1.75 cups.
Therefore, Lenny needs a total of 1.75 cups of borax and washing soda combined.
To determine how many cups of borax and washing soda Lenny needs, we need to calculate the total number of cups needed for both ingredients combined.
The recipe requires 2 parts borax and washing soda for every 1 part soap flakes. Since Lenny is using 7 cups of soap flakes, he would need:
7 cups of soap flakes × 2 = 14 cups of borax and washing soda combined.
Therefore, Lenny needs 14 cups of borax and washing soda combined.
To figure out how many cups of borax and washing soda combined Lenny needs, we first need to determine the ratio between the soap flakes, borax, and washing soda. According to the recipe, the ratio is 2 parts of borax to 2 parts of washing soda to 1 part of soap flakes.
Since Lenny is using 7 cups of soap flakes, we can use this as a reference point to calculate the amount of borax and washing soda needed.
To find the total amount of borax and washing soda, we can add the two parts together. In this case, two parts would equal 2 (borax) + 2 (washing soda) = 4 parts.
Next, we can calculate the amount of each ingredient by dividing the total parts by the number of parts for soap flakes. In this case, we have 4 parts in total and 1 part for soap flakes.
To find the amount of borax and washing soda, we divide 7 cups (the amount of soap flakes) by 1 (the number of parts for soap flakes). This gives us 7 cups.
Therefore, Lenny needs a total of 7 cups of borax and 7 cups of washing soda combined.
