Answer:
2/3 divided by 4/5
First we convert the denominators to a likewise number.
3 and 5 both share 15.
2 x 5 = 10
10/15
4 x 3 = 12
12/15
10/15 divided by 12/15
Correct answer should be 10 over 12.

I believe the last answer would be correct.
Answer: 4 a - 3 b
Step-by-step explanation:
Since, the perimeter of the triangle = sum of all the three side of the triangle.
Here, two sides of the triangle are 2a + b and a - 9b,
And, the perimeter of the triangle = 7 a - 11
Let third side = x
Therefore, 2 a + b + a - 9 b + x = 7 a - 11 b
⇒ 3 a - 8 b + x = 7 a - 11 b
⇒ x = 7 a - 11 b - 3 a + 8 b
⇒ x = 4 a - 3 b ( by operating like terms)
To find out how many brothers they have, they need to multiply 4×1= 4
So there are 4 brothers.
I hope this helped :)
