Question

Denise bought 5.2 pounds of rice for $5.29. How much would 2 pounds of rice cost?

Answer 1

Two pounds of rice would cost `$2.03`.

Explanation:

It is easiest to solve this using a proportion. In the ratios, we will put price over pounds.

`($5.29)/(5.2lb) = x/(2lb)`

Remember to solve proportions, cross multiply.

`$5.29 * 2lb = 5.2lb * x`
`$10.58 lb = 5.2x lb`
`($10.58 lb)/(5.2 lb) = (5.2x lb)/(5.2 lb)`
`$2.03 ~~ x`
