Answer 3

Calculation of the Expression

To calculate the expression 9/5*2+1/4:20, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). In this case, there are no parentheses or exponents involved, so we can proceed with multiplication, division, and addition.

Let's break down the expression step by step:

1. 9/5*2: - First, we perform the division: 9/5 = 1.8. - Then, we multiply the result by 2: 1.8 * 2 = 3.6.

2. 1/4:20: - The division operation here is 1/4, which equals 0.25. - Finally, we divide the result by 20: 0.25 / 20 = 0.0125.

3. Now, we add the results of the previous calculations: 3.6 + 0.0125 = 3.6125.

Therefore, the value of the expression 9/5*2+1/4:20 is 3.6125.

Answer

The value of the expression 9/5*2+1/4:20 is 3.6125.
