Answer 1

Heya Friend!

Sheena here :)

So fractions...

what are fractions?

=> Fractions are numbers which is written in$\frac{x}{y}$ form where x and y and numbers.

=> the vertical line placed after a number is known as "upon"

=>The number written above the upon sign is known as numerator and number which is written below the upon sign is known as denominator.

=> Usually fractional form means dividing the numerator with the denominator.

Coming to your question>>>

The cost of 3 upon 4 article is RS 24 what will be the 1 article cost.

Answer>>>

Let the cost of 1 article be x.

Article                              cost

$\frac{3}{4}$                                       Rs. 24
$\frac{4}{4}$  (1)                                     x

Now cross multiply.

$\frac{3}{4} * x = \frac{4}{4} * 24$
$\frac{3x}{4} = 24$
$3x=24*4$
$3x=96$
$x= \frac{96}{3}$
$x=32$

Therefore the cost of 1 article is Rs. 32

Answer 2

Heya !!
Iam pranu

And here is the explanation for your answer

We can solve this sum in many ways

1. Unitary method

2. Direct and inverse propotion

=≥ in unitary method first' we need to find the cost of one article and the we can multiply the result with the quantity we want

Example :-
Cost of 2 pens = 4/-
Then cost of 4pens = ??

Firstly we need to find the cost of pen
So;
Cost of 1 pen = 4/2 = 2/-
Now cost of 4pens = 2 × 4 = 8/-

This is unitary method

But in the question they asked cost of 1 article
And given

$\frac{3}{4}$ = 24$\frac{3}{4} x = 24/- X = 24 × 4 / 3 X = 8 × 4 X = 32$


So cost of 1 article is 32rupees
