During cooking, chicken losses 10% of its weight due to water loss. in order to obtain 1,170 grams of cooked chicken, how many grams of uncooked chicken must be used?

To calculate how many grams of uncooked chicken are needed to obtain 1,170 grams of cooked chicken, we need to account for the 10% weight loss during cooking.

Let x be the weight of uncooked chicken needed.
After cooking, the weight of the chicken will be 90% of x:
0.90x = 1,170 grams
x = 1,170 grams / 0.90
x = 1,300 grams

Therefore, 1,300 grams of uncooked chicken must be used to obtain 1,170 grams of cooked chicken.
