Answer:
145.6 Calories in 1.3 ounces.
Step-by-step explanation:
We know that one gram is equivalent to 4 calories. We know a pastry is 1.3 ounces of carbohydrates. There are approximately 28 grams in 1 ounce.
There is a way we can find out how to get to 1.3 ounces though.
We need to find out how to get 0.10 ounces. We then need to divide 28 by 10 to get how many grams are in 1/10 of an ounce. If we work that out, we get 2.8 grams per 0.10 ounces.
So now we know how many grams there are per 0.10 ounces. We then multiply that by 10 to get 28, which is already what we know. We need to do 2.8 x 3 to get 1.3, 0.10 × 3.
2.8 × 3 = 8.4, so 28 + 8.4 = 36.4 grams.
36.4 grams are in 1.3 ounces. Since one gram has 4 calories, we multiply it by 4.
36.4 x 4 = 145.6 calories in 1.3 ounces.
Let me know if this helped! :D
