.Arrange in decreasing order 1/2, 2/3, 5/8, 3/4

5/8, 3/4, 2/3, 1/2

Step-by-step explanation:

8 is more than 4, 4 is more than 3, 3 is more than 2.

Step-by-step explanation

3/4= 0.75

1/2= 0.5

2/3= 0.66

5/8= 0.625

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
