Well, start from 100% and work backwards.

It takes 5600 years to get to 50%
Another 5600 years to get to 25%
And a bit under another 5600 to get to 15% (another 5600 years would get it down to 12.5%)

Add the first two 550s to get 1120, and add about 5,000 and see which answer is closest.
In this case, D is closest at 15!w29

There are more exact ways of solving, but for a multiple choice this is faster and efficient nonetheless

Answer:

31/6 or 5 1/6

Step-by-step explanation:

First, turn 1.5 into a fraction as “fraction answer” means it wants a answer in the form of a fraction.

1.5 as a fraction is 1 1/2

So the equation is:

2 1/3 - 1 1/2

Now, turn the mixed fractions into improper fractions.

2 1/3 becomes 7/3 and 1 1/2 becomes 3/2

Now the equation is

7/3 - 3/2

To subtract fractions you must make the denominator (bottom number) the same number by finding the lowest common multiple.

3 and 2’s Lowest common multiple is 6.

When making the denominator 6 you also multiply the numerator.

3 x 2 = 6 and 7 x 2 = 14

So the first fraction is now: 14/6

Now:

2 x 3 = 6 and 3 x 3 = 9.

The other fraction is now 9/6

Now:

14/6 - 9/ = 5/6

Now:

6 - 5/6

Now turn 6 into a fraction.

6/1 - 5/6

Now turn the 6/1’s denominator into 6

6 x 6 = 36; 1 x 6 = 6

36/6 - 5/6 = 31/6

The answer is 31/6!
