pounds. Use estimation to determine about how much more Pedro’s book weighs than Blanca’s.

Answer 1

By estimating the weight of Pedro's book to be 19 pounds and Blanca's book to be 18 pounds, we determine that Pedro's book is approximately 1 pound heavier.

Step-by-step explanation:

The question asks us to estimate how much more Pedro's book weighs than Blanca's book. Pedro's book weighs 19 4 pounds (which seems to be a typo and should likely represent either 19 or 19.25 pounds), and Blanca's book weighs 17 7 pounds (which also seems to be a typo and should likely represent either 17 or 17.75 pounds). When estimating, we round the numbers to the nearest whole number to make calculations easier.

Assuming the correct weights are 19.25 pounds for Pedro's book and 17.75 pounds for Blanca's book, we would round these to 19 pounds and 18 pounds, respectively. Therefore, to estimate the difference in weight, we subtract 18 pounds from 19 pounds, which equals 1 pound. So, we estimate that Pedro's book is about 1 pound heavier than Blanca's book.
