1/2+2/5 yiuuu vg uk kg to ggghjgjvjihjk

The correct answer is 9/10. I am not sure what the rest of your questions says. Sorry but I hope this helps.

I used a calculator so it would be 9/10.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
