solve by method.​

Answer 1

Answer:

Step-by-step explanation:

Let the required number be x

According to the given condition,

4x  = 3x + 4

 5         4

4x = 3x + 16

 5           4

4(4x) = 5(3x + 16)

16x = 15x + 80

16x - 15x = 80

x = 80

the required number is 80

Answer 2

$\large \underline{ \underline{ \text{Question:}}}$

• Four fifth of a number is greater than three forth of the same number by 4. Find th number.

$\large \underline{ \underline{ \text{Solution:}}}$

Let the number is x.

So,

• $\text{The Four fifth of the number is } \frac{4}{5} x.$

And,

• $\text{The Three forth of the number is } \frac{3}{4} x.$

According to Question,

• Four fifth of a number is greater than three forth of the same number by 4.

Written as,

$\implies \frac{4}{5} x = \frac{3}{4} x + 4$

Finding the value of x,

$\implies \frac{4x}{5} = \frac{3x}{4} + 4$

$\implies \frac{4x}{5} - \frac{3x}{4} = 4$

$\implies \frac{16x - 15x}{20} = 4$

$\implies \frac{x}{20} = 4$

$\implies x = 20 \times 4$

$\implies x = 80$

Therefore,

• The value of x is 80.

As we assumed,

• The number is 80.

$\\ \large \underline{ \underline{ \text{Required Answer:}}}$

• The number is 80 (whose its 4/5th is 4 greater than its 3/4th).
