Helen determined she walks about 1,800 steps per 4/5 of a mile. How many steps did she take if she walked 3 miles

Let's simplify this and use a decimal for 4/5. Use a proportion, cross multiply, and solve for x.

0.8/1800 = 3/x

To solve this problem, we can set up a proportion using the information given.

We know that Helen walks 1,800 steps per 4/5 of a mile. In other words, she walks 1,800 steps for every 4/5 mile.

Let's set up the proportion:

1,800 steps / (4/5) mile = x steps / 3 miles

To solve for x, we can cross-multiply and then divide:

(1,800 steps) * (3 miles) = (4/5) mile * x steps

5 * (1,800 steps) * (3 miles) = 4 * x steps

27,000 steps = 4x

Now we need to solve for x, so we divide both sides by 4:

27,000 steps / 4 = x

x = 6,750 steps

Therefore, Helen would have taken 6,750 steps if she walked 3 miles.
