Suppose that 19 inches of wire costs 95 cents. at the same rate, how much (in cents) will 37 inches of wire cost?

0.95/19 = 0.05 cents per inch

37*0.05 = 1.85

it will cost $1.85

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
