Question

25/4% of a weight is 0.25kg. what is 45% of weight

Answer 1

Let x be weight
25/4 % of x = 0.25kg
(25x/4)×100 = 0.25
25x/4 = 25
25x = 25×4
x = 4kg
45% of 4kg = 45×4/100 = 180/100 = 1.8kg

Answer 2

Answer:

45% of weight is 1.8 kg.

Step-by-step explanation:

Given : $\frac{25}{4}$% of a weight is 0.25 kg.

To find : What is 45% of weight ?

Solution :

Let the weight be 'x',

According to question,

$\frac{25}{4}$% of a weight is 0.25 kg.

i.e. $\frac{25}{4}\%\times x=0.25$

$\frac{\frac{25}{4}}{100}\times x=0.25$

$\frac{25}{4\times 100}\times x=\frac{25}{100}$

$x=\frac{25\times 4\times 100}{100\times 25}$

$x=4$

The weight is x=4 kg.

45% of the weight is $45\%\times x$

$\frac{45}{100}\times 4=1.8$

Therefore, 45% of weight is 1.8 kg.
