Use the fact that 1 pound equals about 453.6 grams.

About 1.98 pounds

Practice makes perfect

We want to express 900 grams in pounds. 900 g≈ lb We can do this by using the fact that 1 pound equals about 453.6 grams. Let's write this relationship as a unit ratio. 453.6 g/1lb To perform the conversion, we need to multiply 900 grams by the unit ratio or its reciprocal. Remember, we want to get the weight in pounds, and every unit we do not want has to be divided out.

900 g≈ 900 g * 1 lb/453.6g
900 g≈ 900 g/1 * 1 lb/453.6g
900 g≈ 900 g* 1 lb/1* 453.6g
900 g≈ 900 g* 1 lb/1* 453.6g
900 g≈ 900 * 1 lb/1* 453.6
900 g≈ 900 lb/453.6
900 g≈ 1.984126 ... lb
900 g≈ 1.98 lb

We found that the bakery uses about 1.98 pounds of peaches.
