Question

On a trip, you had to change your money from dollars to British pounds. You got 560 pounds for 800 dollars. How many pounds will you get for 300 dollars?

Answer 1

Use proportions to solve this. Set up the ratios with dollars on the top and pounds on the bottom and then cross-multiply to solve for x. Like this:
`(d)/(p): (800)/(560)= (300)/(x)`. Cross multiplying gives us 800x=168,000. Divide by 800 to get that x = 210. So $300 equals 210 pounds.
