Mrs. Garcia is making bread using a total of 400 grams of gluten free flour. The recipe calls for 70% of the flour to be almond flour. She needs to know how much almond flower to use.

She needs 280 grams of almond flour.

Step-by-step explanation:

This question can be solved using a rule of three.

400 grams is 100% = 1. How much is 70% = 0.7?

400 grams - 1

x grams - 0.7

x = 400*0.7

x = 280

She needs 280 grams of almond flour.

120g

Step-by-step explanation:

70% of flour in 400g is expressed as

= 70/100*400

=0.7*400

=280g

Therefore, the amount of almond flour to be used by Mrs Garcia in making the recipe is

=400g-280g

=120g

Thus, Mrs Garcia requires 120g of almond flour
