The rules for converting fractions with denominators 10, 100, 1000, etc. into decimal fraction:
(i) Count the number of zeroes coming after 1 in the denominator.
(ii) Count an equal number of places in the numerator starting from the unit digit then place the decimal point to the left of the digit reached.
Let us consider some of the following examples;
1. Convert 819/100 to decimal.
Given, 819/100 This explanation will help you
Sequence: -4, 8, -16
rate of increase: -16/8 = -2
If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n.
The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms.
An = -4(-2)^(n-1)
Solving for the 5th term A5, use n = 5
A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64
So the answer is B.
3 has a value of 'ones'
0 has a value of 'tens'
9 has a value of 'hundreds'
5 has a value of 'thousands'
6 has a value of 'ten thousands'
Rounding up 6, its greater than 5 so add 1 to 7 and make all the other figures zero to give:
Answer = 800,000
