Evaluate the formula for degrees Celsius to solve the problem. Then check all that apply.

Use the Celsius conversion formula C = (5/9)(F − 32). Substitute 68 for F, then follow the order of operations by subtracting first: 68 − 32 = 36. Multiply 36 by 5/9 to get 20, so 68°F is 20°C; multiplying before the subtraction would not follow the formula’s parentheses.
