Answer: 7.48
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.
