1. three hundred thousanths
2.add 8 (8+) to the sum of (x+y) 23 and 10 (23+10) so basically 8+(23+10)
3. we remember that pemdas so parenthasees first
add 6.78 and 2.54 to get 9.42
then 34-(9.42)=34-9.42= 24.38
3. 7-(4/5 times 1/3)
pemdas
remember that (x/y) times (z/t)=(xz)/(yt) so 4/5 times 1/3=(4 times 1)/(5 times 3)=4/15
7-(4/15)
7-4/15
6 and 11/15
