320% of 45+ 45% of 320=?Options320230288280

To solve this problem, we need to calculate each part of the equation separately and then add them together.

First, let's calculate 320% of 45. To do this, we convert the percentage to a decimal by dividing it by 100, which gives us 3.2. Then we multiply this by 45:

3.2 * 45 = 144

Next, we calculate 45% of 320. Again, we convert the percentage to a decimal by dividing it by 100, which gives us 0.45. Then we multiply this by 320:

0.45 * 320 = 144

Finally, we add these two results together:

144 + 144 = 288

So, 320% of 45 + 45% of 320 equals 288. Therefore, the correct answer is 288.
