215 83
To complete the subtraction problem \( 215 - 83 \):
\[ 215 - 83 = 132 \]
So, the answer is 132.
Monte enjoys running. He usually takes one of three trails. Trail A is 5 910 miles long. Trail B is 5 17 miles. Trail C is 5 59 miles. Which list has the trails in order from shortest to longest?

First, let's clarify the length of each trail:
- Trail A: 5,910 miles
- Trail B: 5,017 miles
- Trail C: 5,059 miles
Now, we can arrange these from shortest to longest:
- Trail B: 5,017 miles
- Trail C: 5,059 miles
- Trail A: 5,910 miles
So, the correct order from shortest to longest is B, C, A.

To evaluate \( \frac{3}{2} \div \frac{3}{4} \), we can multiply by the reciprocal of the second fraction:
\[ \frac{3}{2} \div \frac{3}{4} = \frac{3}{2} \times \frac{4}{3} \]
Now, multiply the numerators and the denominators:
\[ \frac{3 \times 4}{2 \times 3} = \frac{12}{6} \]
Now, simplify \( \frac{12}{6} \):
\[ \frac{12}{6} = 2 \]
So, the answer is 2.
Kelly walks 4/5 of a mile each day. How many miles does Kelly walk after three days? NOTE: There is a check answer button in the bottom right corner.

To find out how many miles Kelly walks after three days, you can multiply the distance she walks each day by the number of days:
\[ \frac{4}{5} \text{ miles/day} \times 3 \text{ days} = \frac{4 \times 3}{5} = \frac{12}{5} \]
So, Kelly walks 12/5 miles after three days, which can also be expressed as "12 fifths".
Darko found the sum of 324 and 57 to be 894. What error did he make? NOTE: There is a check answer button in the bottom right corner.

Darko did not align the digits by their place value when he set up the problem. - no response given Darko did not regroup correctly after adding the ones digits. Darko did not regroup correctly after adding the ones digits. - no response given Darko multiplied the numbers instead of adding them. Darko multiplied the numbers instead of adding them. - incorrect Darko added 324 and 75 by mistake. Darko added 324 and 75 by mistake. - no response given
To find the error Darko made, let's correctly add 324 and 57:
- Align the numbers by their place values:
324
+ 57
_____
- Add the ones place: \(4 + 7 = 11\). Write down 1 and carry over 1.
- Add the tens place: \(2 + 5 + 1 (carry) = 8\).
- Add the hundreds place: \(3 + 0 = 3\).
Putting it all together, we get:
324
+ 57
_____
381
The correct sum of 324 and 57 is 381, not 894.
The most relevant error in the provided responses is likely that "Darko did not regroup correctly after adding the ones digits." Since he added \(4 + 7\) and didn't handle the carry correctly, he likely miscalculated that part of the addition.
So the answer is: Darko did not regroup correctly after adding the ones digits.
