Answer 2

Answer:

The value of $x$ is $1.2$

explanation: The given is $8:x:5:0.75$

Find the value of $x$.

Solution : Ratio: A ratio in mathematics denotes the number of times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.

Proportion : A mathematical comparison of two numbers is known as proportion. If two sets of supplied numbers increase or decrease in the same ratio, the ratios are said to be directly proportional to each other, according to proportion.

So, $8:x:5:0.75$

       $\frac{8}{x}=\frac{5}{0.75}$

       $8\times0.75=5\times x$

       $\frac{8\times0.75}{5}=x$

       $\frac{6}{5} =x$

       $x=1.2$

Hence, the value of $x$ is $1.2$ .
