I apologize, but there seems to be an error in your calculations. Let's go through the correct calculations step by step:

1/10 of 90: To find 1/10 of 90, you divide 90 by 10: 1/10 * 90 = 9

1/4 of 40: To find 1/4 of 40, you divide 40 by 4: 1/4 * 40 = 10

So, the correct calculations are: 1/10 of 90 equals 9. 1/4 of 40 equals 10.
