Like im gonna need a written answer

Explain your answer using words, and show your work using division of fractions.

3 weeks

Step-by-step explanation:

create a proportion of grass growth rate over time:

(÷1) = (÷x )

=

cross-multiply:

28x = 84

x = 84/28 which is 3

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

10000

step-by-step explanation: divide by 2,
