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
Answer: B
Step-by-step explanation:
Answer:
96 square tiles are needed
Step-by-step explanation:
To calculate this, the first thing we need to do is calculate the total area covered by the rectangular wall.
Mathematically, the area of the rectangle = 16 * 24 = 384 ft^2
The next thing we need to do is calculate the area of the square tiles = L^2 = 2^2 = 4 ft^2
the number of square tiles needed = Area of rectangular wall/Area of square tiles = 384/4 = 96
Answer:
Wow where are the big ideas
Answer:
6 : 5
Step-by-step explanation:
Volume of a cube = s^3
5^3 = 125
Surface area of a cube = 6s^2
6(5^2) = 6(25) = 150
150 : 125
30 : 25
6 : 5
