Hello guys i would love if you guys can me out

12 + 13 + a = 40

if you need to find out A you would add 13 and 12 then do 40 - 25 to find a

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
