then your figure out "what times what" is -81 (they have to be the same number!)

Its -9 and 9

and so you plug that in to get

skad [1K]

Answer:

Answer is 25/56

Step-by-step explanation:

Given that

Katie and her brother are both writing a report. Katie write 7/8 of her report and her brother wrote 3/7 of his report

TO compare these two fractions we have to make both of them have the same denominator.

We find that as such the two fractions have denominators as 7 and 8 and hence Least common multiple is 56

LEt us make equivalent fractions

7/8 = 49/56

3/7=24/56

Difference i.e. Katie wrote more than her brother = 49/56-24/56

=25/56

The first three terms of an arithmetic sequence are as follows.
svet-max [94.6K]

Answer:

9, 3

Step-by-step explanation:

To get from 27 to 21, you subtract by 6. To get from 21 to 15, you must also subtract by 6. Therefore, subtracting by 6 is the pattern. In order to get the next number in the sequence, we must subtract 6 from 15.

15 - 6 = 9

The next number is 9. To find the number after 9, we must do the same thing - subtract 6 from 9.

9 - 6 = 3

The 5th number of the sequence is 3.

I hope this helps and please mark me as brainliest!
