Answer:
8 apples
Step-by-step explanation:
There are 3 apples with a mass of 39 grams, 2 apples with a mass of 40 grams, 1 apple with a mass of 41 grams, and 1 apple with a mass of 43, and lastly one apple with a mas of 44 grams.
First you find the total, 40, then you find how many large or blue there are, 28 then you divide by the total to be 28/40 or 7/10
For 1. To estimate how many sports cards Alberto had, you would round each number to the nearest ten, so 318 would become 320. 273 would then become 270. You would then add those two and would get 590. So, Alberto had 590 sports cards (estimated). If you were looking for the actual answer (not estimated) , you would get 591.
