first you need to find the least common denominator which in this case it is 40. since 5 and 8 both go into 40.
5/8 = 25/40
3/5 = 24/40
25/40 - 24/40 =1/40
does this make sense to you?

Step-by-step explanation:
Hello!
To solve this problem, we will use a system of equations. We will have one number be x and the other y. We will use substitutions to solve for each variable.
x+y=9
x=2y-9
To solve for the two numbers, we need to solve the top equation. The second equation shows that x=2y-9. In the first equation, we can replace 2y-9 for x and solve.
2y-9+y=9
3y-9=9
3y=18
y=6
We now know the value of y. Now we need to find x. We can plug in 6 for y in the second equation to find x.
x=2·6-9
x=12-9
x=3
Just to check, we will plug these two numbers into the first equation.
3+6=9
9=9
Our two numbers are three and six.
I hope this helps!
Answer
Formula

where r is the radius of a circle.
As shown in the image
Diameter of the circle = 16 .3 cm

= 8.15 cm
Put in the formula

As


= 51.2 cm (approx)
Therefore the circumference of a circle is 51.2cm (approx) .
Option (D) is correct .
