Step-by-step explanation:
it looks like there are 10 segments in every integer number. so, we need to express the given numbers in 10ths.
1. -3/5
how many 10ths are these ? there are 2 10ths in every 5th.
so,
-3/5 = -6/10
you check this therefore on the 6th marker left of 0.
2.
1.825 is just a quarter of one segment after 1.8.
so, put a mark a little bit after the 8th mark after 1 on the right. you have to estimate where to make the mark, as there are no precise markers for that size.
3.
-0.65 is half a marker further to the left of 1. (-6/10).
-0.6 is -6/10. and -0.65 is half a marker further out.
4.
0.40 = 4/10
so, you mark the 4th marker to the right of 0.
5.
-1.785 is similar to 2.
it is a little bit before the 8th marker after -1 to the left.
6.
7/8 = 0.875
so, 1 7/8 = 1.875
this is now similar to 2. and 5.
it is a little bit before the 9th marker after 1 to the right.
7.
5/8 = 0.625
so, this is a little bit after the 6th marker after 0 to the right.
8.
-1.575
this is a little bit before the 6th marker to the left of -1.
