Answer:
The number is 4
Step-by-step explanation:
Let the number = 'x'
Reciprocal of 'x' = 1/x
Reciprocal of 2 = 1/2
8 times the reciprocal of 'x' = 
Now multiply both sides by x
Now divide both sides by 2
x = 4
The sum of an infiinte series exists when the ratio is in the interval (-1,1)
Here the ratio is 1/3, then the sum exists.
The formula for this sum is A / (1 -r); where A is the first term and r is the ratio
Then, the sum is [1/3] / [1 -1/3] = [1/3] / [2/3] = 1/2
Answer: 1/2
Answer: 14/25 = 56/100
11/20 = 55/100
14/25 > 11/20
Step-by-step explanation:
The least common multiple of 20 and 25 is 100.
(100 = 20*5, 25*4)
So we can take the common denominator 100.
14*4/25*4 =56/100. ∴14/25 = 56/100
11*5/20*5 =55/100. ∴11/20 = 55/100
56>55
∴56/100 > 55/100
∴14/25 > 11/20
Hope it's good;)
