Accepted Answer

### Problem 9: How many ten - thousands are in 200,000?
# Explanation:
## Step 1: Recall the place value
The value of one ten - thousand is $10,000$. We want to find how many times $10,000$ fits into $200,000$.
## Step 2: Divide to find the number of ten - thousands
We calculate $\frac{200000}{10000}$
$\frac{200000}{10000}=20$
# Answer:
There are 20 ten - thousands in 200,000.

### Problem 10: How many hundred - thousands are in 5,000,000?
# Explanation:
## Step 1: Recall the place value
The value of one hundred - thousand is $100,000$. We want to find how many times $100,000$ fits into $5,000,000$.
## Step 2: Divide to find the number of hundred - thousands
We calculate $\frac{5000000}{100000}$
$\frac{5000000}{100000} = 50$
# Answer:
There are 50 hundred - thousands in 5,000,000.

### Problem 11a: Compare $18\space km$ and $20,000\space meters$
# Explanation:
## Step 1: Convert units to be the same
We know that $1\space km=1000\space meters$, so to convert $18\space km$ to meters, we multiply by 1000.
$18\times1000 = 18000\space meters$
## Step 2: Compare the two values
We have $18000\space meters$ and $20000\space meters$. Since $18000<20000$, we can say $18\space km<20,000\space meters$
# Answer:
$18\space km<20,000\space meters$

### Problem 11b: Compare $1,700\space grams$ and $17\space kg$
# Explanation:
## Step 1: Convert units to be the same
We know that $1\space kg = 1000\space grams$, so to convert $17\space kg$ to grams, we multiply by 1000.
$17\times1000=17000\space grams$
## Step 2: Compare the two values
We have $1700\space grams$ and $17000\space grams$. Since $1700 < 17000$, we can say $1,700\space grams<17\space kg$
# Answer:
$1,700\space grams<17\space kg$

### Problem 11c: Compare $13\frac{1}{2}\space liters$ and $13,500\space milliliters$
# Explanation:
## Step 1: Convert units to be the same
We know that $1\space liter = 1000\space milliliters$. First, convert $13\frac{1}{2}\space liters$ to an improper fraction: $13\frac{1}{2}=\frac{27}{2}$ liters. Then convert to milliliters: $\frac{27}{2}\times1000 = 13500\space milliliters$
## Step 2: Compare the two values
We have $13500\space milliliters$ and $13500\space milliliters$. So $13\frac{1}{2}\space liters = 13,500\space milliliters$
# Answer:
$13\frac{1}{2}\space liters = 13,500\space milliliters$

### Problem 12: Riley ran a 10K in 1 hour and another 10K in 58 minutes. How much faster was the second 10K run?
# Explanation:
## Step 1: Convert 1 hour to minutes
We know that $1\space hour=60\space minutes$
## Step 2: Find the difference in time
The time for the first 10K is 60 minutes and for the second is 58 minutes. To find how much faster the second run was, we subtract the time of the second run from the time of the first run.
$60 - 58=2\space minutes$
# Answer:
The second 10K run was 2 minutes faster.
