Question
Abe correctly rounded all of the values to the nearest ten to estimate and then used a calculator to determine the exact value of the expression. 542-360 ÷ (472 - 442) Which statements are true about Abe's estimated result and calculated result for this expression? Check all that apply. Abe's exact answer is 530. Abe's estimated answer is 528. Abe's exact answer is 528. Abe shouldn't use a calculator on the first step (472 - 442) because it is easily done using mental math. O The first step in evaluating the expression is to subtract 360 from 548.
