Question

Four bags of potatoes weigh 3.35 pounds, 4.894 pounds, 5.6 pounds, and 4.95 pounds. What is the total weight of the bags?

Answer 1

18.8

if you sum the 4 numbers you get 18.794, but you need to round to nearest tenth, as that's the best reliable number, 5.6

if you rounded to 2 decimals you'd still get 18.79. Which is very close to 18.8
