CALCULATE
Question 1.
Which is larger, a 2-liter bottle of soda or a 2-quart bottle?
Answer:
Convert from liter to quarts.
1 liter = 1.05 quart
2 liter = 2 × 1.05 = 2.11 quart
2.11 quart > 2 quart
Therefore 2-liter bottle of soda is larger than a 2-quart bottle.
Question 2.

1 meter = 39.37 inch
2 meters = 2 × 39.37 = 78.74 inch
Therefore 2-meter long snake is 78.74 inch
Question 3.
A man weighs 91 kilograms. How many pounds is that?

Question 4.
The police officer said that you were traveling at a speed of 100 kilometers an hour. How many miles per hour were you traveling?
Answer:
Given,
The police officer said that you were traveling at a speed of 100 kilometers an hour.
We have to convert from kilometer to mile.
1 kilometer = 0.62 mile
100 kilometer = 0.6 × 100 = 62 miles
Thus you were traveling 62 miles per hour.
Question 5.
The weight limit on a bridge is 15,000 kilograms. How many tons is that?
Answer:
Given,
The weight limit on a bridge is 15,000 kilograms.
Convert from kilograms to tons.

15000 kg = 15000 × 0.0011 = 16.53 tons
Question 6.
100 meters is how many yards?
Answer:
Convert from meter to yards.
1 meter = 1.09 yard
100 meter = 100 × 1.09 = 109 yards
Thus 100 meters is 109 yards.
Question 7.
Is $5.00 a gallon for gas more than $1.75 a liter?
Answer:
Convert from gallon to liter
1 gallon = 3.78 liters
1 liter = $1.75
3.78 liters = 3.78 × 1.75 = $6.61
Thus $5.00 a gallon of gas is not more than $1.75 a liter
Question 8.
7 liters of water is about how many quarts?

1 liter = 1.05 quart
7 liters = 7 × 1.05 = 7.39 quarts
Question 9.
Which is shorter, 15 millimeters or .75 inches?
Answer:
Convert from millimeter to inch to find which is shorter.
1 millimeter = 0.039 inch
15 millimeters = 15 × 0.039 = 0.59 inch
0.59 < 0.75
So, 15 millimeters is shorter than 0.75 inches.
Question 10.
Which is larger, a 200-gram steak or a \(\frac{1}{2}\) pound one?
Answer:
Convert from pound to gram
1 pound = 453.6 grams
\(\frac{1}{2}\) = 453.6/2 = 226.8 grams
Thus \(\frac{1}{2}\) pound is larger than 200 gram steak.
