you can calculate this by making a fraction of 28/64 and timing this by 100!

Solution:

Note that:

  • 64 × x/100 = 28

Simplifying the LHS:

  • 64 × x/100 = 28
  • => 64x/100 = 28

Using cross multiplication:

  • 64x/100 = 28
  • => 64x = 2800

Divide 64 both sides.

  • => x = 2800/64 = 43.75%

28 is 43.75% of 64
