A number can be divided by 14, 35 and 42. The maximum number is______ ．

14 = 2 × 7, 35 = 5 × 7, 42 = 2 × 3 × 7, so the greatest common divisor of 14, 35 and 42 is 7

When estimating divisor is a division of one digit, the divisor is generally regarded as the number of (), () or (), and the divisor remains unchanged. The basic method of oral division is used for calculation

When estimating division is a division of one digit, the divisor is generally regarded as (whole hundred) (whole ten) or (several hundred and dozens) (several thousand and hundreds), and the divisor remains unchanged. The basic method of oral division is used for calculation

Xiaoqin went out on a road trip. On the first day, he traveled 6 hours by car, 2 hours by foot, 2 hours in total, 218 kilometers in total. On the second day, he traveled 4 hours by car, 3 hours by foot, 152 kilometers in total. How many kilometers does he travel and walk?
2 hours in total
Please give me a specific answer!

218 + 152 = 370km, this is 10 hours by car + 5 hours by walk
370 △ 5 = 74 km is 2 hours car + 1 hour walk
218-152 = 66 km, 2 hours by car - 1 hour by walk
Therefore, 74-66 = 8 km is a 2-hour walk, and that 1-hour walk is 4 km
218-4x2 = 210 / 6 = 35 km
I wonder if you understand

One third of a number is five more than one fourth of it. Find the number
Let this number be x, 1 / 3 X-1 / 4 x = 5,
The solution is x = 60
P35
7 out of 10 is (1 / 10). It has (7) such fractional units
The difference between the subtracted and the subtracted is equal to 8. If the subtracted is doubled and the subtracted remains unchanged, the difference increases by 300%, and the subtracted is (16). [subtracted: 8 × 300% = 24, subtracted: 24-8 = 16]

3 × (4-1) + 1 = 10

What is 2 (x-1) 3 = - 125 / 4?

The original formula is (x-1) 3 = - 125 / 8, so X-1 = - 5 / 2, so x = - 3 / 2

A 2-meter-long rectangular steel is cut into two sections. The surface area is 16 square decimeters larger than the original. What is the original volume of this steel

After truncation, the surface area is increased by two times of the bottom area of the cuboid steel
So its volume = bottom area × height = (16 △ 2) × (2 × 10) = 160 (cubic decimeter)

It's easier to simplify than to apply,
The distance between a and B is 80 kilometers. It takes three fourths of an hour for a truck and 0.8 hours for a bus. The speed ratio between the bus and the truck is written and simplified
A typing task, a to 6 hours to complete, B to complete the time is two-thirds of a, write a, B efficiency ratio, and simplify

1. Speed ratio of passenger car to freight car (80 ／ 3 / 4): (80 ／ 0.8) = 16:15
2. The ratio of work efficiency of Party A and Party B: 1 / 6: [1 ÷ (6 × 2 / 3)] = 1 / 6:1 / 4 = 2:3

1.08 L = () CC 2 000 CC = () ml = () l 5 cubic decimeter 8 cc
1.08 liter = () cubic centimeter 2000 cubic centimeter = () milliliter = () liter 5 cubic decimeter 8 cubic centimeter = () cubic decimeter（

1.08 L = (1080) cm3, 2000 cm3 = (2000) ml = (2) l, 5 cm3, 8 cm3 = (5.008) cm3
The rate between two adjacent units is (1000)

A mathematics (geometry) problem in volume two of grade one of junior high school
In triangle ABC, angle a = 96 degrees, extend BC to point D, the bisector of angle ABC and angle ACD intersects at point A1, the bisector of angle a1bc and angle a1cd intersects at A2, and so on, what is the degree of angle A5 if the bisector of angle a4cd and angle a4bc intersects at A5?

A1=96/2=48°
A2=48/2=24°
A3=24/2=12°
A4=12/2=6°
A5=6/2=3°
