Take some onomatopoeia

Who knows how to calculate these questions easily?
(1)5.6÷3.5
(2)15.05÷35
(3)26.4÷0.25-1.4+0.25

1).(5.6÷0.7)÷(3.5÷0.7)
=8÷5
=1.6
2).(15+0.05)÷35
=15÷35+0.05÷35
=3/7+1/700
=300/700+1/700
=301/700
3) There is no solution for the moment

Seeking ratio and reducing ratio
Ratio: 2 / 4:5= Simplification ratio: 4:2 / 5=_

4: 2 out of 5, that is, 2 out of 0.8. Divide the preceding term by the following term. 0.8 divided by 2 equals 0.4 or 2 out of 5
When the reduction ratio is increased by 10 times at the same time, it is 20 out of 8, then it is reduced, and divided by the greatest common divisor 4, it is 2 out of 5

Ratio reduction and ratio calculation
1. Simplification ratio
1 / 6: 1 / 5 = ()
50：
2 / 3: 7 / 8=
2. Calculate the ratio
15.7：5=
0.2:1 / 7=
0.31：2=

1. Simplification ratio
1 / 6:1 / 5 = (5:6)
50:5 / 10 = 100:1
2 / 3:7 / 8 = 16:21
2. Calculate the ratio
15.7：5= 15.7/5=3.14
0.2:1 / 7 = 0.2 * 7 = 1.4
0.31：2=0.31/2=0.155

18: 27 | 38 of 95 | 2 / 3: 5 / 6 | 12: 8 / 9
------No need for simplification ratio------------------------------------------------
The following is to simplify the ratio and find the ratio
6.4:4.8 | 2. | 4 out of 35: 16 out of 21|
--------------------------------------------------------------------
The ratio is calculated and simplified
The speed of sound in the air is 340 meters per second. The maximum speed of a jet bus is 578 meters per second
Write the ratio of edge length, ground area, surface area and volume of a and B cubes and simplify them
Small cube: 4cm long side, big cube, 6cm long side
Why do I have to answer after I've finished

578/340=17/10
Edge length ratio = 4 / 6 = 2 / 3 area ratio = 16 / 36 = 4 / 9 surface area ratio = 96 / 216 = 4 / 9
Volume ratio = 64 / 216 = 8 / 27

Seeking ratio and simplifying ratio
Ratio
(1) What is the ratio of 3 / 2:0.75
(2) What is the ratio of 0.8:4 / 15
Simplification ratio
(1) 1 / 4: 15
(2) 12:3 / 4 reduction ratio

Original formula = 3 / 0.75 / 2 = 2
Original formula = 0.8 * 4 / 15 = 3
Original formula = 1 / 15 / 4 = 1 / 60
Original formula = 12 * 4 / 3 = 16

The significance of simplification ratio

Reduction ratio refers to the simplest integer ratio, such as
32：48=2：3
Pay attention to the score
5/2：3/7=35：6

Please summarize your problem here, simplify first, and then evaluate 1 / 3A ^ 2B + 5a-2 (3AB ^ 2-A ^ 2b) - 3 (3a-4ab ^ 2)
Where a = - 3, B = - 1 / 2

Original formula = 7 / 3 × a ^ 2b-4a + 6ab ^ 2
=121/18
