Question

What should be added to the product of 2 , 4 by 7 (a mixed fraction ) to 3 to get 21, 5 by 14 (a mixed fraction). Pls give me a answer

Answer 1

Answer:

18 ¹¹/14

Step-by-step explanation:

Here you should not have mention 3. Because it is is becoming a mistake in the question. so excluding the 3, I am solving the problem.

Let us take the number that should be added as x

Now, 2 ⁴/7 = ¹⁸/7

i.e

• ¹⁸/7 + x = 21 ⁵/14
• ¹⁸/7 + x = ²⁹⁹/14
• x = ²⁹⁹/14 - ¹⁸/7
• x = ²⁶³/14
• x = 18 ¹¹/14

Ans :- The number that should be added is 18 ¹¹/14.
