7, 11, 13, 25, 125, 8 and 4 It's better to be more detailed and list several formulas

For example, 385,38-2 × 5 = 28 = 7 × 4, so 385 is a multiple of 7. For example, 6139,613-2 × 9 = 595,59-2 × 5 = 49 = 7 × 7, so 6139 is a multiple of 7

A = 1 / 100 + 1 / 101 + 1 / 102 - + 1 / 499 + 1 / 500, then what is the integer part of a?

The integral part of a is 1

How to calculate (1-101 / 1) * (1-102 / 1) * (1-103 / 1) * ·· * (1-110 / 1)?
And how to calculate with (1-2 / 1) * (2-3 / 2) * (3-4 / 3) * · * (7-8 / 7)? It's better to explain why

（1-101/1）*（1-102/1）*（1-103/1）*···*（1-110/1）
=(100/101)*(101/102)*(102/103)*···*（109/110)
=100/110
=10/11
（1-2/1）*（2-3/2）*（3-4/3）*···*（7-8/7）
=(1/2)*(4/3)*(9/4)*（16/5）*(25/6)*(36/7)*（49/8）
=630

How many liters and milliliters is seven twentieth cubic decimeter

7 / 20 cubic decimeter = 0.35 liter = 350 ml
If you don't understand this question, you can ask. If you are satisfied, please click "select as satisfactory answer"

Five and two hundredths of a cubic decimeter equals () liters () milliliters

Because one cubic decimeter equals one liter
So 5 (13 / 200) cubic decimeters = 5 (13 / 200) liters
One liter = 1000 ml
13 / 200 L = 1000 (13 / 200) ml = 5 (13) ml = 65 ml
So five and two hundredths of a cubic decimeter is five liters and 65 milliliters
I hope that will help you. If you have any questions, please remember to adopt them

5 liters 80 ml = cubic decimeter

5 liter 80 ml = 5.08 cubic decimeter

15 liter 260 ml = () cubic decimeter 5 cubic decimeter = () cubic meter

15.26

3. How many milliliters is 5 liters. How many cubic decimeters is 125 milliliters

5000 ml
0.125 cubic decimeter

3.08 L, 3 cubic decimeter, 800 cubic centimeter, 3 L and 8 ml (from large to small)

08 l > 3 L 8 ml > 3 cubic decimeter > 800 cubic centimeter

From small to large, 3.08 liters 3 cubic decimeters 800 cubic centimeters 3 liters 8 ml

3 L 8 ml < 3.08 L
