Answer:
4/7 = 8/14
Step-by-step explanation:
Add 5 on both sides
Make the denominators the same

Multiply 13 on both sides


2/5+3/8= 31/40 therefore he still has 9/40 to go.
to get this you multiply the two denominators together
5x8=40 which is your denominator
then you cross multiply the two numerators
2x8=16
3x5=15
to get the final
15/40+16/40=31/40
and you are left with 9/40
I believe the answer is -26 :) I hope this helps! ^_^
