Answer:
4. 3
Step-by-step explanation:
If you multiply 2 by 3 it'll equal to 6. Same with 7 x 3= 21.
You could also subtract 7 from 2 equalling 5 and 21 - 6 equal to 15. Then you would but y over x giving you 15/5. 15 divided by 5 is 3. So both ways you get 3.
Hope that helps :)
It's 13=13. Add the numbers in the parenthesis first! So it would be 9+4=8+5, then just add them up and you get 13 on each side!
You can write 6/9 as a decimal or in simplest fraction form.
Divide 6 and 9 by 3, which will give you 2/3.
6/9 equals 0.66... (repeating).
