1. The amount of sugar in a 2-liter bottle of orange juice is 176 grams.2. The amount of butter needed to make 150 cookies is 15 sticks.
Explicación
## Step 1:The first question is about the concept of proportionality. The problem states that a 250 mL glass of orange juice contains 22 grams of sugar. We are asked to find out how much sugar is in a 2-liter (2000 mL) bottle of orange juice. ## Step 2:To solve this, we need to set up a proportion. The proportion is set up as follows:###
## Step 3:Next, we solve for
by cross-multiplying and dividing.## Step 4:The second question is about the concept of ratios. The problem states that it requires two sticks of butter to make a batch of 20 cookies. We are asked to find out how much butter will it take to make 150 cookies.## Step 5:To solve this, we need to set up a proportion. The proportion is set up as follows:###
## Step 6:Next, we solve for
by cross-multiplying and dividing.
