Answer: 75 pages
Step-by-step explanation:
3/10 of 2/3
= 3/10 * 2/3
= 2/10; simplified by dividing by 2 = 1/5
1/3 + 1/5 = 8/15
Let x represent the amount of pages left
so, 7/15 x = 35
x = 75
Therefore, there are 75 pages in the book
Answer: 2/3
Step-by-step explanation:
3/5 divided by 9/10 = 3/5 x 10/9
I got 30/45 which simplifies to 2/3
Answer:
1000 times greater
Step-by-step explanation:
9.6 * 10^-2 / 9.6 * 10^-5
= (9.6 / 9.6) * (10^-2 / 10^-5)
= 1 * 10^(-2 -( -5))
= 10^3
= 1000

I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
As given in the question, we know that:
The ratio of the area of the circle to the area of the square is π/4
- The formula to find the volume of the cone is:
V = 1/3*the height*the base area
<=> V1 = 1/3*h*π
- The formula to find the volume of the pyramid is:
V2 = 1/3*the height*the base area
<=> V = 1/3*h*4
=> the ratio of volume of the cone to the pyramid is:
= 
= (1/3*h*π
) / ( 1/3*h*4
)
= π/4
S we can conclude that the volume of the cone equals π/4 the volume of the pyramid
Hope it will find you well.
