Mary has 5 2/5 yards of string. Written as an improper fraction, 5 2/5 = 27/5 yards of string.
The friend was given 2/3 of the string. The friend received 2/3 * 27/5 = 18/5 yards which is the same as 3 3/5 yards and also 3.6 yards.
After Mary gave the friend the string, Mary had 27/5 - 18/5 = 9/5 yards left.
9/5 yards is the same as 1 4/5 yard and also 1.8 yards.
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.
