Answer 1

#6

Given:

`(2)/(5)=(8)/(\square)`

Asked: Find the missing denominator.

Solution:

To find the missing denominator, we need to know what was multiplied to 2 that became 8.

We can then multiply the factor to 5 to get the missing denominator.

To find the factor, we will divide the numerators:

`\begin{gathered} (2)/(5)=(8)/(\square) \\ (8)/(2)=4 \end{gathered}`

The factor is 4. Now we will multiply 4 to the denominator 5 to get the missing denominator.

`\begin{gathered} (2)/(5)=(8)/(\square) \\ (2)/(5)\cdot(4)/(4)=(8)/(20) \end{gathered}`

ANSWER: 20
