Let's find a common factor for the two denominators (10 and 8) to make the two fractions combinable.

We need to find a number that can be divisible by 10 and 8 (denominators). Right off the bat, we can just multiply the two numbers and get 8 x 10 = 80.
Then let's make the numerators correspond to the denominators.

8/10 = x/80 Set up a proportion.
10x = 640 Cross-multiplication.
x = 64 Divide and simplify.

3/8 = x/80 Set up a proportion.
8x = 240 Cross-multiplication.
x = 30 Divide and simplify.

Now we have 64/80 (originally 8/10) and 30/80 (originally 3/8). Now which one is the larger number?

64/80 > 30/80
8/10 > 3/8

8/10 would be greater because 3/8 is not as close as 8/10 to being a whole the one that's closest to a whole is always the answer. Hope It helped!

Answer from: Quest

use an equation of ratios to determine the amount of gas needed to fill the tank.

0.2 0.8

288.75 x

231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal $3

* = $3465 (answer)

1 1 gal

hope this you

Answer from: Quest

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m 60 second 60 minutes

* * = 54000 meters/ hour

second 1 minute 1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m 1 km

* = 54 km / hours

hour 1000m
