Question

1. write 0.300 in word form

2. write an expressions for the calculation add 8 to the sum of 23 and 10
3. 34 - ( 6.78 + 2.54 )
4. 7 - ( 4 over 5 time 1 over 3 )

Answer 1

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
