PSSR #7: Measuring Sticks
Yvonne, Sid, Madeline, and Asher each have a different kind of measuring stick. Pach
stick is marked with equally spaced units, but the spaces are not necessarily the same
from one stick to another, Yvonne's, Sid's and Asher's sticks each have been broken off
at the beginning of their scales. Madeline's stick is not broken. Yvonne's stick starts at
11 units, Sid's stick starts at 33 units, Madeline's stick starts at 0 since it is not broken.
Asher's stick starts at 17 units
Each of the four students measured the depth of a pond at the same pot, Yvonne's stick
read 91 units deep, Sid's stick read 113 units deep, Madeline's stick read 160 units deep,
Asher's stick read 177 units deep
LEVEL 1
LEVEL 2
LEVEL 3
Do any of these students
have the same units of
measurement on their
sticks Which ones?
Asher took his stick and
measured Madeline's
height, and his stick read
89 units,
What reading would
Yvonne's stick give for
Madeline's height:
How many of Yvonne's
units would Madeline be?
Level 3 pls

12/60 students chose science fiction

Approximately x/150 students prefer sf

60x = 1800

x = 30

30/150 students are assumed to prefer sf

30/150 = x/100

150x = 3000

x = 20

20/100 students are likely to prefer sf

Mr. Rodriguez made a reasonable estimate for the approximate percentage of students that prefer science fiction, because if 12/60 is equivalent to 30/150 which refers to the number of students who can be assumed to prefer science Fiction out of the whole school. Considering we need to identify what 30/150 as a percentage is, we can reduce it down to 1/5 to make I easier, then divide 1 by 5 to get .2
.2 as a percentage is 20%, so his inference was indeed reasonable.
