Answer:
11/19 chance
OR
roughly 57% chance.
Step-by-step explanation:
If we add our marbles, we have a total of 19 marbles to pick from. 11 of those marbles are green. This means we have a 11/19 chance of picking two green marbles.
If you want to find the percentage then do this:
We know that we have a 11/19 chance. To find the percentage, we would need to turn the fraction into a decimal first.
11÷19≈0.579
To turn a decimal into a percentage, we would need to multiply the decimal by 10 (move the decimal two spaces to the right.)
That would give us 57.9%.
So, you have, approximately, a 57% chance of picking two green marbles.

1/100
Step-by-step explanation:
The answer is:
1/4d
( / means it is a fraction)
If the length of rectangular school hall is 4 times the width and the perimeter be 55m, then the length is 22m and the width of the school hall be 5.5m.
Given that the length of rectangular school hall is 4 times the width.
We are required to find the length and breadth of the rectangle which has the length be 4 times the width.
Perimeter of rectangle is the sum of all the length and breadth of that rectangles.
Perimeter of rectangle is given as 55m
Perimeter=2(L+B)
let the width of rectangle be x.
Length of that rectangle be 4x.
According to question,
2(x+4x)=55
2*5x=55
10x=55
x=55/10
x=5.5 m
Width be 5.5 m.
Length of rectangle be 4*5.5=22m.
Hence if the length of rectangular school hall is 4 times the width then the length is 22m and the width of the school hall be 5.5m.
