Equation 1: 7 equals 100%
Equation 2: 'x' equals 90%

Step 6: To solve for 'x', we divide equation 1 by equation 2, considering that both equations have the same unit (%). Thus, we obtain:
7 / x = 100% / 90%

Step 7: By taking the reciprocal of both sides of the equation obtained in Step 6, we have:
x / 7 = 90 / 100
⇒ x = 6.3

Therefore, we conclude that 90% of 7 is equal to 6.3.
