Question

If 3/4 th of a number is 60 , then , half of the number is
​

Answer 1

Answer:

The required number is 80.and,

Half of that number is 40.

Step-by-step explanation:

let the number be x ,

ATQ,

3/4 × x = 60

0.75 × x = 60

x = 60/0.75

x = 80

Therefore the required number is 80

Now ,half of the number is..,

80 × 1/2

80 / 2 = 40

Therefore half of the number is 40.

Answer 2

Given:

If 3/4 th of a number is 60.

To Find:

half of the number.

Solution:

↬First let's find the original number

so,let the original number be x

$: \implies \sf\frac{3}{4} x = 60 \: \: \: \: \: \: \\ \\ : \implies \sf \: \frac{3x}{4} = 60 \: \: \: \: \: \: \\ \\ : \implies \sf3x = 60 \times 4 \\ \\ : \implies \sf 3x = 240 \: \: \: \: \: \\ \\ : \implies \sf \: x = \cancel \frac{240}{3} \: \: \: \: \\ \\ : \implies \sf \: x = 80 \: \: \: \: \: \: \: \:$

$\blue{ \boxed{ \purple{ \mathfrak{ \therefore the \: original \: number = 80}}}}$

half of the original number:

$: \implies \sf \: \frac{1}{2} \times 80 \\ \\ : \implies \sf\frac{1}{ \cancel{{2} }} \times \cancel{ 80} \\ \\ : \implies \sf40 \: \: \: \: \: \: \:$

$\blue{ \underline{ \boxed{ \pink{ \mathfrak{ \therefore \: half \: of \: the \: number = 40}}}}}$

hope this helps.!!
