The decimal 0.363636... repeats without ending, so it's non-terminating and recurring.
It cannot be a terminating decimal since it doesn’t end.
It is a rational number but not a linear or quadratic fraction in this context.
Let's denote the unknown number as x.
Given that 3/4 of 28 is equal to 21/5 of x:
(3/4) * 28 = (21/5) * x
First, calculate 3/4 of 28:
(3/4) * 28 = 21
Now, equate this to 21/5 of x:
21 = (21/5) * x
Multiply both sides by 5:
105 = 21x
Divide both sides by 21:
x = 105 / 21
x = 5
A mile is a unit of measurement for distance.
A litre is a unit of measurement for liquid — this is a similar relationship.
To find the greatest possible length of a scale that can measure exactly 3 meters, 5 meters 40 centimeters, and 13 meters, we need to determine the greatest common divisor (GCD) of these measurements.

A number is divisible by 4 if the last two digits form a number that is divisible by 4.
The last two digits of 9128 are 28, and 28 ÷ 4 = 7, which is divisible by 4.
Cost per student: 1 3/8 = 11/8
Total amount: 13 3/4 = 55/4
Now, divide the total amount by the cost per student:
Number of students = Total amount ÷ Cost per student
= (55/4) ÷ (11/8)
= (55/4) × (8/11)
= 55 × 2 / 11
= 110 / 11
= 10
To find when all three tests will be conducted together again, we need to find the least common multiple (LCM) of 3, 6, and 9.
The LCM of 3, 6, and 9 is 18.
So, all three tests will be conducted together again after:
18 days
1 kilometer equals 10 hectometers.
1 kilometer (km) = 1000 meters
1 hectometer (hm) = 100 meters
Therefore, 1 km = 1000 meters / 100 meters/hm = 10 hectometers
By Using formula
2n+1=23
⇒ n=11
