Answer 1

`\sf A) (60)/(40) \textsf{ and } D)(3)/(2) \textsf{ or } 1.5`

Explanation:

In order to simplify
`\sf (12)/(40) \cdot 5`, we can use the following definitions:

Multiplication: The multiplication of two numbers is the process of adding the two numbers together a certain number of times.

Division: The division of two numbers is the process of splitting one number into a certain number of equal parts.

Solution:

We can simplify \tex]\sf \dfrac{12}{40} \cdot 5 [/tex] by multiplying the two numerators and the two denominators:

`\sf (12 \cdot 5)/(40 \cdot 1) = (60)/(40)`

We can also simplify
`\sf (60)/(40)` by dividing the numerator and denominator by 20:

`\sf (60 / 20)/(40 / 20) = (3)/(2)`

Therefore, all simplified expressions are:

`\sf A) (60)/(40) \textsf{ and } D)(3)/(2)`
