I couldn't see properly sorry
8,276
39
[]
student
yea
8,276
40
[]
volunteer
okay so the first step is to make the mixed number an improper fraction
8,276
41
[]
volunteer
do you know how to do that?
8,276
42
[]
student
I'm lagging
8,276
43
[]
volunteer
its okay take your time
8,276
44

student
here
8,276

okay so the first step is to make the mixed number an improper fraction
8,276
46
[]
student
there
8,276
47
[]
volunteer
do you know how to do that?
8,276
48
[]
student
no
8,276
49
[]
volunteer
do you know what a mixed number is?
8,276
50
[]
student
yea when it's a whole number next to a fraction
8,276
51
[]
volunteer
okay good
8,276
52
[]
volunteer
how about improper?
8,276
53
[]
student
A improper is when the bigger number is on top and the smaller number is on the bottom
8,276
54
[]
volunteer
yes thats right!!
8,276
55
[]
volunteer
so to start with this question
8,276
56
[]
volunteer
we need to make 1 1/2 an improper fraction
8,276
57
[]
student
W
8,276
58
[]
volunteer
ill show you how on the whiteboard
8,276
59
[]
volunteer
soo
8,276
60
[]
student
11/2
8,276
61
[]
volunteer
to get it, we multiply 2 by the whole number, then we add the numerator
8,276
62
[]
volunteer
nope, its not 11/2
8,276
63
[]
student
2
8,276
64

L
8,276
65
[]
student
2
8,276
66
[]
volunteer
yes
8,276
67
[]
volunteer
then you add 1
8,276
68
[]
volunteer
what do you get?
8,276
69
[]
student
yaa
8,276
70
[]
student
nope .-.
8,276
71
[]
volunteer
no
8,276
72
[]
volunteer
its not done yet Chloe
8,276
73
[ { "pii_type": "PERSON", "surrogate": "Chloe", "start": 17, "end": 22 } ]
student
ok
8,276
74
[]
volunteer
there are more steps
8,276
75
[]
volunteer
so what's 2 x 1 + 1?
8,276
76
[]
student
:(
8,276
77
[]
student
3
8,276
78
[]
volunteer
its okay its easy
8,276
79
[]
volunteer
okay so
8,276
80
[]
volunteer
the numerator of the improper fraction will be 3, while the denominator will stay as 2
8,276
81
[]
student
.-.:)
8,276
82
[]
student
ok
8,276
83
[]
volunteer
so the improper fraction is 3/2
8,276
84
[]
volunteer
can you show me the whole problem again?
8,276
85
[]
student
yea
8,276
86
[]
volunteer
okay so now it is 1/4 divided by 3/2
8,276
87
[]
volunteer
the first step is to make it a multiplication expression
8,276
88
[]
volunteer
do you remember how to do that?
8,276
89
[]
volunteer
what does 3/2 become?
8,276
90
[]
student
idk
8,276
91
[]
volunteer
you just flip the numbers
8,276
92
[]
volunteer
what does it become when you flip 3/2?
8,276
93
[]
student
8,276
94
[]
student
2/3
8,276
95
[]
volunteer
yes
8,276
96
[]
volunteer
so now u multiply
8,276
97
[]
volunteer
1/4 x 2/3
8,276
98
[]
volunteer
what's the answer?
8,276
99
[]
student
2/12
8,276
100
[]
volunteer
yess that's right!!!
8,276
101
[]
volunteer
now you need to simplify once again
8,276
102
[]
volunteer
what's the GCF of 2 and 12?
8,276
103
[]
student
uhhh
8,276
104
[]
student
1
8,276
105
[]
volunteer
greatest common factor
8,276
106

student
2
8,276
108
[]

111
[]
volunteer
2
8,276
112
[]
student
ok
8,276
113
[]
volunteer
so you divide both numbers by 2
8,276
114
[]
volunteer
2 divided by 2 and 12 divided by 2
8,276
115
[]
volunteer
what's the answer for both?
8,276
116
[]
student
Ifg (I forgot)
8,276
117
[]
volunteer
okay
8,276
118
[]
volunteer
what's 2 divided by 2?
8,276
119
[]
student
1
8,276
120
[]
volunteer
okay so that's our numerator
8,276
121
[]
volunteer
what's 12 divided by 2?
8,276
122
[]
student
6
8,276
123
[]
volunteer
okay good, that's our denominator
8,276
124
[]
volunteer
so the final answer is..?
8,276
125
[]
student
2/6
8,276
126
[]
volunteer
nope, what's 2 divided by 2 again?
8,276
127
[]
volunteer
its not 2
8,276
128
[]
student
1/6
8,276

[]
volunteer
yes
8,276
130
[]
volunteer
good job
8,276
131
