Answer:
<u>Mika estimated the sum to be 216; the actual sum is 216.27.</u>
Step-by-step explanation:
Let's find the rounded sum and the actual sum, as follows:
Rounding each number to the nearest whole:
189.27 ⇒ 189
15.8 ⇒ 16
11.2 ⇒ 11
Sum = 189 + 16 + 11
Sum = 216
Actual sum:
Actual sum = 189.27 + 15.8 + 11.2
Actual sum = 216.27
<u>Mika estimated the sum to be 216; the actual sum is 216.27.</u>
Answer:
Step-by-step explanation:
The verbiage "five and nine tenths" can refer to the mixed number 5 9/10, or to the decimal in standard form, 5.9. Simply converting the phrase to a decimal gets you the standard form.
The expanded form can be written a number of ways, depending on how you like to show the place value multipliers. The simplest expanded form is simply the sum of the digits:
5 + 0.9
You can show the multipliers in standard form:
5×1 + 9×0.1
Or, you can show the multipliers in exponential form:
5×10⁰ +9×10⁻¹
