we have
1) -1/10
step 1
Between the number 0 and number 1 there are 10 spaces
so
each space is
(1-0)/10=1/10
so
-1/10 is 1 space at left of zero
answer part 1 is C
part 2) we have
1/5
Remember that
1/5 is equivalent to 2/10
so
2 spaces at right of zero
answer part 2 is D
Part 3) we have
9/10
correspond to 9 spaces at right of zero
answer part 3 is F
Part 4) we have
-0.5
-0.5=-1/2=-5/10
5 spaces at left of zero
answer part 4 is B
Part 5) we have
0.6
0.6=6/10
6 spaces at right of zero
answer part 5 is E
Part 6) we have
-4/5
-4/5=-8/10
8 spaces at left of zero
answer part 6 is A
