Solution:

Step-1: Convert the ratios into fractions.

  • 5:7 = 35:49
  • 5/7 = 35/49

Step-2: Simplify both sides of the fraction.

~5/7 cannot be simplified because the numerator and denominator are prime number. However, 35/49 can be simplified by dividing 7 to the numerator and the denominator.

  • 35/49 ⇒ 7 x 5/7 x 7 ⇒ 5/7

⇒ 5/7 = 35/49

⇒ 5/7 = 5/7 (Yes. They are equal)
