Question

1) Don works 18 hours a week. Which expression shows a good way to use rounding to estimate how many hours Don will work in 52 weeks? Name 5.1 B A 10 X 50 B 10 X 60 C 20 X 50 0 18 X 60

Answer 1

Since Don works 18 hours a week, we can round up to 20, and since we are estimating how many hours Don will work in 52 weeks, we can round down to 50, so we can estimate the total hours with the expression 20 x 50
