Question

What should be subtracted from 4/7 - 2/3 to get 3/5 (class 7 rational number)

Answer 1

Answer:

Let the known number be = x

According to the question

$\frac{ 4}{7} - \frac{2}{3} - x = \frac{3}{5} \\ \\ = \frac{12 - 14 - 21x}{21} = \frac{3}{5} \\ \\ = \frac{ - 21x - 2}{21} = \frac{3}{5} \\ \\ = 5( - 21x - 2) = 3(21) \\ \\ = - 105x - 10 = 62 \\ \\ = - 105x = 72 \\ \\ x = \frac{ - 72}{105} \\ \\ x = \frac{ - 24}{35}$
