65. change 11 5/6 to a mixed number:
71/6-17/18
multiply 6 and 71 by 3 which equals 18 so now the denominators are the same
213/18-17/18=196/18
to simplify divide 196 and 18 by 2
196÷2=98
18÷2=9
now divide 98 by 9
98÷9=10 (rounded to whole number)
9×10=90
so to get 98 you add 8
your answer is 10 8/9
66. change both fractions to a mixed number
9 5/9=86/9
8 1/6=49/6
multiply 86 and 9 by 2
86×2=172
9×2=18
multiply 49 and 6 by 3
49×3=147
6×3=18
now subtract :
172/18-147/18=25/18
divide 25 by 18
25÷18=1 (rounded whole number)
18×1=18
to get 25 you add 7
your answer is 1 7/18
hope this helped
i would use TIBO:
*top in bottom out*
a/b (a over b form)
you divide the numerator (a) from the denominator (b)
and example is 5/10 if you use TIBO you should get 0.5
hope it helps!
Answer:
YES
Step-by-step explanation:
------------------------------------------------------------------
Information Given
------------------------------------------------------------------
Total Cost of the stamps = $9.00 - $1.75 = $7.25
Total number of stamps = 60
Value of the $0.10 stamp = $0.10
Value of the $0.15 stamp = $0.15
------------------------------------------------------------------
Assumed all $0.10 stamps.
------------------------------------------------------------------
Assumed all the 60 stamps she bought were $0.10 stamps.
$0.10 x 60 = $6.00
------------------------------------------------------------------
Find amount not accounted for.
------------------------------------------------------------------
Amount of money not accounted for:
$7.25 - $6.00 = $1.25
The $1.25 must had been used to pay for the $0.15 stamps.
------------------------------------------------------------------
Find difference in values between the two stamps.
------------------------------------------------------------------
Difference in the value of the two stamps:
$0.15 - $0.10 = $0.05
------------------------------------------------------------------
Find number of $0.15 stamps
------------------------------------------------------------------
Number of $0.15 stamps = $1.25 ÷ $0.05 = 25
There were 25 $0.15 stamps.
------------------------------------------------------------------
Find number of $0.10 stamps.
------------------------------------------------------------------
Number of $0.10 stamps = 60 - 25 = 35
There were 35 $0.10 stamps.
------------------------------------------------------------------
Answer: 35 $0.10 stamps and 25 $0.10 stamps.
------------------------------------------------------------------
I maybe be wrong I think it is called a Divisor?
