Question

I need the answer for this problem?

Answer 1

27) $\frac{5}{9}$ = $\frac{15}{27}$

This is because 5 x 3 is 15. Whatever you do to the top, you do to the bottom. 9 x 3 is 27.

31) $\frac{5}{7}$ = $\frac{25}{35}$

This is because 7 x 5 is 35. So you times 5 by 5 too.

Hope this helped :)

Answer 2

For the first one the number 5 goes into 15 3 times and you need to do the same to both top and bottom so to get the answer you need to times 9 by 3. Which gives you 27 so the answer for the first one would be
15:27.

For the second question you would do exactly the same as the first divide 35 by 7 which gives you 5 you then times 5 by 5. Which gives you 25. So the answer for the second would be 25/35.


15/27
25/35
