The error is the exponent in the answer should be 11.
Step-by-step explanation:
When you move the decimal place one spot as they do in the final step to move it from a base 10 to a base 1, we have to add a exponent on. Therefore, it should go from 10 to 11.
Take 3.27 and divide that by 1.09 (for the oranges) 3.27/1.09=3lbs. of oranges then take 4.76 and divide that by 1.19 (for the pears) 4.76/1.19=4lbs. of pears add 4+3 to get how many lbs. in all 4+3=7
