Question
Alex had 12 gumball machines. Each had about 47 gumballs. Using compatible numbers, what is the best estimate for the number of gumballs Alex had?Alex had about gumballs.
Solution
To estimate the total number of gumballs Alex had, we can round the number of gumballs in each machine to a number that is easier to work with.
Step 1: Round the number of gumballs in each machine. 47 is close to 50, so we can use 50 as a compatible number.
Step 2: Multiply the number of gumball machines by the estimated number of gumballs in each machine. Alex had 12 gumball machines and we are estimating 50 gumballs per machine, so 12 * 50 = 600.
So, Alex had about 600 gumballs.
