I need help with these problems. The 1st one is: [2/5+2/15]/1
2nd: 7/2/[8/9x7/8]. I went to a website for help with these problems. For the first answer they gave 8/15. And for the second 9/2x-1. I wasn't sure about the second one, but the first one just didn't seem right. Please help and workout.

The firsts answer is 8/15 and the seconds is 2 13/18. Use the BODMAS technique.

2/5 + 2/15
before we can add them - the denominators must be the same
so multiply 2/5 times 3/3 = 6/15
6/15 + 2/15 = 8/15 - the answer is correct
