- kobby is 5 years younger than Nana
Four years later Nana will be twice as
old as kobby Find their present ages.
-

Kobby is 1 and Nana is 6

Step-by-step explanation:

lets mark Kobby's present age x, than Nana's present age would be x+5.

four years later Kobby's age would be x+4, and Nana's x+5+4, or 2(x+4).

so

x+5+4=2x+8

x-2x=8-5-4

-x=-1

x=1

her total is 2

  -3+5=2

5/12

step-by-step explanation:

give them both a common denominator so you get 9/12 and 4/12. subtract 9/12 from 4/12 to get 5/12.
