One unit of lumber is 3.7 inches wide, and another is 1.6 inches wide. How much wider in inches is the first unit of lumber than the second?

In military time (24-hour clock), times in the morning are the same as in regular time except without the "AM" designation and usually with a leading zero for times before 10:00 AM.

Therefore, 5:00 AM is simply written as 0500 in military time.

Set up a proportion where the ratios must be equal.

=

This can be solved by cross-multiplying:

200×𝑋=2×20

200𝑋=40

Now, solve for X by dividing both sides by 200:

𝑋= ​= 0.2

Thus, the value of X is 0.2.

To find 3 percent of 60, calculate 3% as a decimal, which is 0.03, and then multiply it by 60:

0.03×60=1.8

This means 3 percent of 60 is 1.8.

The correct answer is: C 1.8

To convert the decimal 0.16 to a fraction, follow these steps:

1. Write it as a fraction of 1:

0.16=

1. Multiply both the numerator and the denominator by 100 to eliminate the decimal places (because there are two decimal places in 0.16):

=

1. Simplify the fraction by finding the greatest common divisor (GCD) of the numerator and the denominator: The GCD of 16 and 100 is 4, so divide both the numerator and the denominator by 4:

=

The correct fraction representation of 0.16 is therefore ​.

So the answer is B 4/25.
