Let's solve each part of the question step by step:
Convert 1423 (military time) to standard time:
Military time 1423 is the same as saying 14:23 hours.
To convert military time to standard time, subtract 12 from hours greater than 12: 14 − 12 = 2
Therefore, 1423 military time in standard time is 2:23 PM.
Convert 320 mcg to mg:
To convert micrograms (mcg) to milligrams (mg), divide by 1,000 because 1 mg is equal to 1,000 mcg: 1000 320 = 0.32
Therefore, 320 mcg is equal to 0.32 mg.
Convert 3.5 cups to ounces:
One cup is equal to 8 ounces.
To find the equivalent in ounces, multiply the number of cups by 8: 3.5 × 8 = 28
Hence, 3.5 cups is 28 ounces.
Convert 12 lbs, 4 ounces to kg (round to the nearest tenth):
First, convert the entire weight to ounces.
1 pound is equal to 16 ounces, so 12 lbs is 12 × 16 = 192 ounces.
Adding the 4 ounces, we get 192 + 4 = 196 ounces.
Now, convert ounces to kilograms. There are approximately 35.274 ounces in a kilogram.
35.274 196 ≈ 5.561 kg
Rounding 5.561 to the nearest tenth, we get 5.6 kg.
Therefore, the conversions are:
2:23 PM
0.32 mg
28 ounces
5.6 kg
