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.
If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144. That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2. So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.
