estimate the total weight of two boxes that weigh 9.4lb and 62.6 lb using rounding and compatible numbers. Which estimate is closer to the actual total weight? why?
thanks!

9 + 63 = 72 using rounding which happens to be exact and I also call 9 and 63 compatible numbers since adding 9 to anything is super easy.

10 + 62 = 72 lbs.
9 + 63 = 72 lbs. 
9+63=72 or 10+62

Estimate the total weight of two boxes that weight 9004 lb in 62000 or 6 lb using rounding and compatible numbers which estimate is closer to the actual total weight why
