Question

thrice of a number added with(-4/7) then the result multiplied by 1/2 and it gives 11/14 find the answer​

Answer 1

Step-by-step explanation:

Let the number be x

So,

$\\ (3x + \frac{ - 4}{7} ) \times \frac{1}{2} = \frac{11}{14} \\ = 3x + \frac{ - 4}{7} = \frac{11}{14} \div \frac{1}{2} \\ = 3x + \frac{ - 4}{7} = \frac{11}{14} \times \frac{2}{1} \\ = 3x = \frac{11}{7} - \frac{ - 4}{7} \\ = 3x = \frac{11 - ( - 4)}{7} \\ = 3x = \frac{11 + 4}{7} \\ = 3x = \frac{15}{7} \\ = x = \frac{15}{7} \div 3 \\ = x = \frac{15}{7} \times \frac{1}{3} \\ x = \frac{5}{7}$

So the Number is 5/7
