He didn't follow the pemdas rule<u> (see explanation)</u>
Step-by-step explanation:
Rayan's mistake is that he didn't follow the pemdas rule, which states that you start with wat is inside parentheses first, then exponents then multiplication and division(from left to right) and then adding and subtracting (from left to right).
Let's set this ratio up as a fraction: (successful field goals)/(field goal attempts) There were 439 successful field goals and 937 attempts: 439/937 The fraction cannot be reduced, so the ratio is 439/937.
