Question

How much should be added to 7/20 in order to get 3?​

Answer 1

Answer:

Number =

$\frac{7}{10} or0.7$

Both are same and correct ☺️

Step-by-step explanation:

Let X be the number that should be added to 7/20 to get 3

Then A.T.P ( according to the problem)

7/20 + X = 3

$\frac{7 + 20x}{7} = 3$

( By taking LCM then transporting 7 to RHS )

7 + 20x = 3×7

7 + 20x = 21

20x = 21 - 7

$x = \frac{14}{20}$

$x = \frac{7}{10} \: or \: 0.7$
