You just take the denominator of the fraction used to divided the one and there is your answer. does this help
If

is odd, then

while if

is even, then the sum would be

The latter case is easier to solve:

which means

.
In the odd case, instead of considering the above equation we can consider the partial sums. If

is odd, then the sum of the even integers between 1 and

would be

Now consider the partial sum up to the second-to-last term,

Subtracting this from the previous partial sum, we have

We're given that the sums must add to

, which means


But taking the differences now yields

and there is only one

for which

; namely,

. However, the sum of the even integers between 1 and 5 is

, whereas

. So there are no solutions to this over the odd integers.
<u>Complete Question with table is attached</u>
<u>Answer:</u>
Miguel will save money of $90 if he earns $120.00
<u>Step-by-step explanation:</u>
The figure attached clearly shows the ratio of his earnings and savings. We have to find what would be the savings amount if he earn $120.00. So, first we have to calculate the percentage of ratio of his earnings and savings. As per the data given in the figure,
If he earns $10.00, he saves $7.50, calculate %amount he saves as below,

Likewise, calculate for all given data. If he earns $50.00 then he saves $37.50

If he earns $150.00 and save $112.50,

So, from all above, it clearly tells that Miguel saves 75% of amount from his earnings. Now, given earnings as $120.00. By finding 75% of $120.00, we can find his savings in that amount. So,
