Final answer:
To evaluate the expression a=7/22*(3.14+2)*3/5;, follow the order of operations (PEMDAS) and perform the calculations step by step.
Step-by-step explanation:
To evaluate the expression a=7/22*(3.14+2)*3/5;, we follow the order of operations, also known as PEMDAS. First, we perform the addition inside the parentheses: (3.14 + 2) = 5.14. Then, we multiply by 7/22, which gives us 5.14 * 7/22 = 1.6436364. Finally, we multiply by 3/5, resulting in a value of approximately 0.9861818.
