Answer 2

It seems like you're trying to find the missing value in the given fractions. Let's solve each of these step by step:

1. 4/5 = 4 : ?

   To find the missing value (denominator) in the ratio, we can set up a proportion:

   $4/5 = 4/x$, where $x$ is the missing value.

   Cross-multiply: $4x = 5 \times 4$

   $x = \frac{5 \times 4}{4}$

   $x = 5$

   So, $4/5 = 4 : 5$

2. 3/4 = ? : 4

   Set up the proportion:

   $3/4 = x/4$, where $x$ is the missing value (numerator).

   Cross-multiply: $3 \times 4 = 4x$

   $12 = 4x$

   $x = \frac{12}{4}$

   $x = 3$

   So, $3/4 = 3 : 4$

3. 1/8 = 1 : ?

   Set up the proportion:

   $1/8 = 1/x$, where $x$ is the missing value.

   Cross-multiply: $1x = 8 \times 1$

   $x = \frac{8 \times 1}{1}$

   $x = 8$

   So, $1/8 = 1 : 8$

In each case, we found the missing value in the given ratio.
