How to calculate the unit rate of volume?

Lower unit higher unit (Division)
Higher unit lower unit (multiplication)

Write the value of a after the operation of the following expression, let a = 12, n = 5. Both a and N are defined as integer variables
(1)a%=(n%=2),(2)a\=a+a,(3)a+=a-=a*=a

(1)a=12%(n%2)=12%1=0
(2)a=a/(a+a)=0
(3)a=a*a=144;
a=a-144=0;
a=a+0=0;
Finally, a = 0

If int a = 12 and N = 5 are defined, what is the value of a after the operation of the expression a% = (n% 2)?

First calculate n% 2, because n = 5, the value of N% 2 is 1 (%, which means modulus, i.e. remainder)
Then we calculate a = a% 1, so the final value of a is 0

If loga radical 2 > loga radical 3, then the value range of a is

0

2.5 M3___ Cubic decimeter___ L =___ Ml

2.5 cubic meters = 2500 cubic decimeters = 2500 liters = 2500000 ml; so the answer is: 250025002500000

A and B start from a and B at the same time and travel in opposite directions. A travels 80 kilometers per hour, and B travels 10% of the whole journey per hour. When B reaches 58, a reaches B at 16 of the whole journey. How many kilometers are there between a and B?

The speed ratio of a and B is: (1-16): 58 = 56:58 = 4:3; therefore, the speed of B car per hour is: 80 △ 4 × 3 = 20 × 3 = 60 (km); the distance between AB and a: 60 △ 10% = 60 △ 0.1 = 600 (km); a: the distance between a and B is 600 km

Know the length, thickness and width of aluminum strip, how to calculate the weight without density
What is the density?

The density of aluminum is 2.73. To know its weight, we need to use length * width * thickness * density and workability

X = what? 5x-4 = 40 5 (x-4) = 40 (48-3x) △ 3 = 0 x + 5x-7
X = what?
5X-4=40 5(X-4)=40 (48-3X)÷3=0
X+5X-7=11

After a cylinder is cut off 5 cm, the surface area of the cylinder is reduced by 31.4 square cm. What is the original surface area of the cylinder? Its height is 20 cm
2. Divide the ground of a cylinder into two parts equally. This is that the surface area has increased by 14 square decimeters. What is the original bottom area of the cylinder?

Divide 20 by 5 and multiply by 31.4

It is known that a * 3 is 1 / 3 = 11 / 12 * b = 15 / 15 * C. and A.B.C is not equal to 0. Arrange the three numbers of A.B.C from small to large, and say why? We need a process

Let them all equal one
Then a is less than 1, B is greater than 1, C = 1
