If you mean the fraction 23/15, divide 23 by 15. The whole part will be the whole number; the remainder will be the numerator for the fractional part.
Subtract 8 from 38; divide by 2 for the first number; add 8 for the second number. Example: 38 - 8 = 30 / 2 = 15 (first number). 15 + 8 = 23 (second number). Proof: 15 + 23 = 38.

Each number is 8 more than the preceding number.
15-23 = -8

To find the total number of sections on the spinner, we use the theoretical probability formula. If the probability of spinning an even number is ( \frac{23}{x} ) and there are 8 even-number sections, we set up the equation: ( \frac{8}{x} = \frac{23}{1} ). Solving for ( x ) gives ( x = \frac{8 \times 1}{23} ), which implies there are 184 sections on the spinner (since ( x = \frac{8 \times 1}{23} ) leads to ( 8 \times 23 = 184 )). Thus, the spinner has 184 sections in total.
23-8 = 15
23 - 8 = 15
