Answer:
≈ 94.7% is an A grade.
Step-by-step explanation:
In order to solve this problem, we first have to find out what percentage 322 out of 340 is. To do that, we have to divide 322 by 340.
322 / 340
When we divide these numbers, we get 0.947, if we round to the nearest thousandth.
For us:
A+ = 97 - 100%
A = 94 - 96%
A - = 90 - 93%
If we convert 0.947 to a percentage (move the decimal point two spaces to the right), then we get 94.7, which goes under the A category.
