Answer 2

Answer:

The conversion rate is found to be: €1 = $1.25

Step-by-step explanation:

Unitary Method:

The unitary method is a method of finding the value of one unit and then finding the value of the required number of units.

Suppose you go to the market and buy 6 apples. The owner says he sells 10 apples for 100 rupees. In this case, the apple is the unit and the price of the apple is the value. When solving problems using the unitary method, it is important to know the units and values.

For simplicity, always write what is calculated on the right side and what is known on the left side. In the above problem,  the amount of  apples is known and the value of  apples is unknown.

Calculation:

The estimation of Euro to Dollar is given to us such that:

Number of dollars in €4: $5

Number of dollars in €1: $5/4

Or by simplifying, we can say:

€1 = $1.25

Thus, the conversion rate is found to be $1.25 dollars in a euro.
