Question

(c) 4:6::8:x
please friends tell me answer who will find answer I make him brainly ​

Answer 1

Answer:

Given:-

Solve, 4 : 6 : : 8 : x.

To Find:-

The value of "x".

Note:-

●》Here, the product of extremes = product of means. Extremes - The first and fourth term, Means - The second and third term.

●》Transposing is also required for finding "x". Transposing is a process in which we change the side of "known value" for finding "unknown value" and also sign are changed. For example - Multiple becomes Divisional.

Solution:-

$\huge\red{4 : 6 : : 8 : x}$

$\huge\red{ \ \ The \ \ value \ \ of \ \ x = ?}$

☆ According to note first point ( Extremes = 4,x; Means = 6,8 )~

▪︎$4 : 6 : : 8 : x$

▪︎$4 × x = 6 × 8$

▪︎$4x = 48$

☆ According to note second point ( Transposing )~

▪︎$x = \dfrac{48}{4}$

☆ After dividing~

▪︎$x = 12$

$\huge\pink{The \ \ value \ \ of \ \ x = 12}$

Checking:-

♤ Let's check for "x" by Product of extremes = Product of means or not.

• $Product \ \ of \ \ extremes = Product \ \ of \ \ means \implies ?$

• $4 × x = 6 × 8 \implies ?$

♤ Applying "x" value~

• $4 × 12 = 6 × 8 \implies ?$

• $48 = 48 \implies ✔$

$\huge\green{Hence, Proved : x = 12}$

Answer:-

Hence, The value of "x" = 12.

Answer 2

Answer:

The value of $x$ is 12.

Step-by-step explanation:

In context to the question asked,

We have to find the value of $x$

As per data given in the question,

We have,

$4:6::8:x$

In the form of fraction it is written as:

$=> \frac{4}{6}=\frac{8}{x}$

By using the cross multiplication method,

=> 4 $\times$ $x$ = 8 $\times$ 6

Multiply the numbers,

=> 4$x$ = 48

Divide both sides by 4,

=> $x = 1 2$

Hence, the required value of x is 12.
