1.Kori spent $46.20 on 12 gallons of gasoline. What was the price per gallon?
A.$8.35
B.$3.85
C.$2.59
D.$0.26
2.a rabbit can run short distances at a rate of 35 miles per hour. A fox can run short distances at a rate of 21 miles per half hour. Which animal is faster, and by how much?
A. The rabbit; 7 miles per hour
B. The fox; 7 miles per hour
C. the rabbit; 14 miles per hour
D. The fox; 14 miles per hour
3.Randy walks 1/2 mile in each 1/5 hour. How far will Randy walk in one hour?
A.1/2 mile
B.2 miles
C.2 1/2 miles
D.5 miles

1: B $3.85

2: C The rabbit; 14 miles per hour

3: C 2 1/2 miles

1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85

2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.

Subtract: 35-21= 14. So the rabbit is faster by 14 miles.

3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:

1/2 mile = 1/5 hour

1 mile = 2/5 hour

1 1/2 mile = 3/5 hour

2 mile = 4/5 hour

2 1/2 mile = 1 hour

So, Randy will travel 2 1/2 miles in a hour.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
