If a 56-gram serving of pasta contains 7 g of protein, how many grams of protein are in a 454 gram box of the pasta?

Answer 1

Step 1 - Build equations from word problem

(1) 56g of pasta = 7g of protein

(2) 454g of pasta = X of protein

Step 2 - Get each equation equal to one.

(1) 56 g of pasta / 7 g of protein = 1

(2) 454 g of pasta / X g of protein = 1

Step 3 - Set them equal to each other and solve

X = 7g of protein * 454 g of pasta / 56 g of pasta

X = 56.75 g of protein

Answer 2

the 454 box is 454/56 bigger, so you need the same factor increase of 454/56 x 7 g of protein

454/56 x 7 = 454/8 = 56 3/4 grams of protein
