Question

what should be added to 5/7 to get 5/3?(step by step)​

Answer 1

Step-by-step explanation:

$\frac{5}{7} + x = \frac{5}{3} \\ x = \frac{5}{3} - \frac{5}{7} \\ = \frac{(5 \times 7) - (5 \times 3)}{3 \times 7} \\ = \frac{35 - 15}{21} \\ x = \frac{20}{21}$

Answer 2

Answer:

let the number be x

• $\frac{5}{7} + x =\frac{5}{3}$

⇒ $x = \frac{5}{3}-\frac{5}{7}$

⇒ $x = \frac{35}{21}-\frac{15}{21}$

⇒ $x=\frac{35-15}{21}$

⇒$x = \frac{20}{21}$
