`5//7 "of" 567+2/5 "of" 485=?`

Options

A. 525
B. 652
C. 599
D. 585

Answer

To solve the problem `5/7 of 567 + 2/5 of 485`, we will follow these steps:

### Step 1: Calculate \( \frac{5}{7} \) of 567
To find \( \frac{5}{7} \) of 567, we multiply 567 by \( \frac{5}{7} \).

\[ \frac{5}{7} \times 567 = \frac{5 \times 567}{7} \]

### Step 2: Simplify the multiplication
First, we can divide 567 by 7:

\[ 567 \div 7 = 81 \]

Now, multiply by 5:

\[ 5 \times 81 = 405 \]

So, \( \frac{5}{7} \) of 567 is 405.

### Step 3: Calculate \( \frac{2}{5} \) of 485
Now, we find \( \frac{2}{5} \) of 485 by multiplying 485 by \( \frac{2}{5} \):

\[ \frac{2}{5} \times 485 = \frac{2 \times 485}{5} \]

### Step 4: Simplify the multiplication
First, divide 485 by 5:

\[ 485 \div 5 = 97 \]

Now, multiply by 2:

\[ 2 \times 97 = 194 \]

So, \( \frac{2}{5} \) of 485 is 194.

### Step 5: Add the two results together
Now we add the results from Step 2 and Step 4:

\[ 405 + 194 = 599 \]

### Final Answer
Thus, the final answer is:

\[ \boxed{599} \]
