Marizza181 [45]

3/45 = 20/x...3 in to 45 seconds = 20 in to x seconds

(3)(x) = (45)(20)
3x = 900
x = 900/3
x = 300...300 seconds (or 5 minutes)to fill the tub with 20 inches

To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add $\frac{1}{2} \ and \ \frac{1}{3}$ . Add $\frac{1}{2} \ and \ \frac{1}{3}$ , and remove the chance for both the black slack shirt and outfit and are one of the six outfits:
