1. 2 libras de naranjas.
2. 5 libras de naranjas.
3. ( x ) libras de naranjas.

Explanation:

1. For 2 pounds of oranges

Step1: Identify the cost per pound

The cost per pound of oranges is $\$1.25$.

Step2: Calculate the total cost for 2 pounds

To find the total cost, we multiply the cost per pound by the number of pounds. So, the formula is $Total\ Cost = Cost\ per\ pound\times Number\ of\ pounds$. Substituting the values, we get $1.25\times2$.

Step3: Perform the multiplication

$1.25\times2 = 2.5$

Step1: Identify the cost per pound

The cost per pound of oranges is $\$1.25$.

Step2: Calculate the total cost for 5 pounds

Using the formula $Total\ Cost = Cost\ per\ pound\times Number\ of\ pounds$, we substitute the values: $1.25\times5$.

Step3: Perform the multiplication

$1.25\times5 = 6.25$

Step1: Identify the cost per pound

The cost per pound of oranges is $\$1.25$.

Step2: Calculate the total cost for \( x \) pounds

Using the formula $Total\ Cost = Cost\ per\ pound\times Number\ of\ pounds$, we substitute the number of pounds with \( x \). So the total cost is $1.25\times x$, which can be written as $1.25x$.

Answer:

$\$2.5$
