Rational numbers can be written as fractions.

The square root of four is an example of a rational number.

A and D

Step-by-step explanation:

The answers are A, B and D.

A- All fractions are rational numbers, so this is true.

B- As I said in A, all fractions are rational numbers, but not repeating decimals.  For an example pi is a repeating decimal but is not rational. So this is not true.

C- Pi is not a rational number since it cannot be put as a fraction. The fraction for "pi" is 27/2, but this is only for a part of pi. So this is incorrect and not true.

D- The square root of 4 is 2, and integers are rational numbers so this is true.

E- A integer divided by 0 is undefined so this is incorrect and not true.

the probability is 0

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
