48 is what percent of 642

7.48

Step-by-step explanation:

Let the missing percent be x.

The question implies: 48 = x% of 642

Which means x/100 × 642 = 48

Multiply the numerators = x × 642 = 642x

Multiply the denominators= 100 x 1 = 100

Therefore, 642x /100 = 48

Then, cross multiply:

642x = 100 x 48

642x = 4800

Divide both sides by 642 to get the value of x

x = 4800/642

x = 7.48.
