To find out how much flour Mariam needs to use, we can look at the ratio between the amount of baking powder used and the amount of flour used. In this case, the ratio of baking powder to flour is 25 g : 720 g.
To calculate how much flour Mariam needs to use with 25 g of baking powder, we can set up a proportion:
25 g / X g = 720 g / 1
To solve for X, we can cross-multiply:
25 * 1 = 720 * X
25 = 720X
Next, divide both sides of the equation by 720 to solve for X:
X = 25 / 720
X ≈ 0.0347
Therefore, Mariam needs to use approximately 0.0347 grams of flour.
Next, to calculate how much baking powder Mariam needs to use with 720 g of flour, we can set up another proportion using the new ratio of baking powder to flour:
25 g / X g = 720 g / 1
Again, we can cross-multiply:
25 * 1 = 720 * X
25 = 720X
Next, divide both sides of the equation by 720 to solve for X:
X = 25 / 720
X ≈ 0.0347
Therefore, Mariam needs to use approximately 0.0347 grams of baking powder.
Lastly, if Mariam wants to bake 4 cakes, we can multiply the amounts of baking powder and flour needed for a single cake by 4 to find the total amounts needed for 4 cakes.
For baking powder:
0.0347 g * 4 = 0.1388 g
Therefore, Mariam needs approximately 0.1388 grams of baking powder for 4 cakes.
For flour:
0.0347 g * 4 = 0.1388 g
Therefore, Mariam needs approximately 0.1388 grams of flour for 4 cakes.
