Question

Priya's family exchanged 300 dollars for 5,100 pesos. Priya bought a sweater for 340 pesos. How many dollars did the sweater cost?

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

300 dollars = 5100 pesos

340 pesos = sweater cost (pesos)

x = sweater cost (dollars)

Step 02:

300 dollars ---------------------- 5100 pesos

x ---------------------- 340 pesos

x * 5100 = 300 * 340

`x\text{ = }(300\cdot340)/(5100)=(102000)/(5100)=\text{ }20`

The answer is :

The sweater cost $ 20.
