Chester needs 2 feet of ribbon for an art project but his ruler only measures in centimeters. there are 12 inches in 1 foot and 2.54 centimeters in 1 inch

60.96 cm

Step-by-step explanation:

To find the amount Chester needs using his centimeter ruler, convert 2 feet into inches and then into centimeters.

Each foot has 12 inches so 2*12 = 24 inches. 2 feet is 24 inches.

To find the number of centimeters, 24 inches * 2.54 cm = 60.96 centimeters

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
