If you estimate 342 ÷ 7 by using 350 ÷ 7 by using 350 ÷ 7 = 50, is 50 greater than or less than the exact answer? How did you decide? Is 50 an overestimate or an underestimate?
its more than the exact answer because you would round 342 to 340 because 350 is an overestimate. I decided because when your rounding you only round up if the ones place value is larger than 5 but in this case its not.
