22 digits that means it goes from 10-99, excluding numbers such as 11, 22, 33, 44, 55, 66, 77, 88, 99. Therefore, the amount of secret numbers is 81. The probability of someone guessing it is 1/81.

A vender bought an earphone for $1378 and she sold it in order to make a profit of 17. 5% calculate the profit made in cash and
Inessa [10]

The profit he made from selling his hearing aids at a profit of 17% is $234.26.

<h3>How to calculate the profit obtained?</h3>

To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.

  • $1,378 ÷ 100 = $13.78
  • $13.78 × 17 = $234.26

Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.

$1,378 + $234.26 = $1,612.26

How to use denominators when comparing two fractions with the same numerators
Sholpan [36]
What you would do is take the denominators and multiply them by each other, then multiply the numerators by that same number. So like 4/10 and 4/9. You would say, (denominators) 10x9=90 and (numerators) 4x9=36. So your first fraction would be 36/90. Next, you would take (denominators) 9x10=90 and (numerators) 4x10=40. So your second fraction would become 40/90. Now it's a lot easier to compare. 36/90 < 40/90 would be the answer to my problem. I hope I helped!
