Answer:
11 grades of 85 did Brenda, Robert, and Timothy receive altogether.
Step-by-step explanation:
Let 6x be the number of 85 received by Brenda.
The number of 85 received by Robert is 1/3 of Brenda= 2x
The number of 85 received by Timothy is 1/2 of Brenda= 3x
Then according to the given conditions
6x+ 2x+ 3x
= 11x
So the number of total 85s received by all the three is 11.
11 grades of 85 did Brenda, Robert, and Timothy receive altogether.

How to determine the values</h3>
It is important to note that a percentage is the number or ratio expressed as a fraction of 100.
It is denoted using the percent sign, "%"
a. What number is 53% of 43
= 53/ 100 × 43
= 0. 53 × 43
= 22. 79
b. 43% of 300
= 43/ 100 × 300
= 129
c. 12% of what number is 43
12/ 100 × x = 43
x = 43 × 100/ 12
x = 358. 3
d. 43 is what percent of 106
43/106 × 100/ 1
4300×/ 106
40. 5%
e. What percent of 43 is 6
43/ 100 × 6
2.58%
Thus, the percentage of a value is that value divided by 100
