Step-by-step explanation:
Answer:
is a factor of 
Step-by-step explanation:
is a factor of
We will prove this with the help of principal of mathematical induction.
For n = 1, is a factor , which is true.
Let the given statement be true for n = k that is is a factor of 
.
Thus, can be written equal to 
, where y is an integer.
Now, we will prove that the given statement is true for n = k+1
Thus, is divisible by .
Hence, by principle of mathematical induction, the given statement is true for all natural numbers,n.
Estimate of the quotient:
3 3/7 = 3+0.428571=3.428571
1 4/9 = 1+0.444444=1.444444
(3 3/7) / (1 4/9) = 3.428571 / 1.444444 = 2.373627
Estimate of the quotient: 2.373627
Exact quotient:
3 3/7=(7*3+3)/7=(21+3)/7=24/7
1 4/9=(9*1+4)/9=(9+4)/9=13/9
(3 3/7) / (1 4/9) = (24/7) / (13/9) = (24/7)*(9/13)=(24*9) / (7*13)=216/91
Exact quotient: 216 / 91 = (182+34) / 91 = 182 / 91 + 34 / 91 = 2 34/91
Exact quotient: 216/91 = 2 34/91
