A table is 10 yuan more expensive than a chair. The chair is three fifths of the table

A table is 10 yuan more expensive than a chair. The chair is three fifths of the table

If the table price is x, the formula is as follows:
X-10=3/5X
2/5X=10
X = 25 yuan
Chair = 25-10 = 15 yuan

There are 48 books in the book corner of 5 (3), of which comic books account for 5 / 16 and story books account for 7 / 16
What's the percentage of the total? What's the percentage of other books?

5/16 + 7/16 = 12/16 = 3/4
1 - 3/4 = 1/4
These two kinds of books account for 3 / 4 of the total. Other books account for 1 / 4 of the total

What is the simplification ratio of 27:54

27:54
The simplest common factor = 27
So 27:54
=27/27:54/27
=1:2

If you want to measure the length of a large coil of bare copper wire, you can use a scale to measure the total mass m of the coil of copper wire, use a scale to measure the length l0 of a small section, and then use a balance to measure it
If the mass of this section of copper wire is m, then the total length of the coil of copper wire L =?

Density = mass / volume, the density of the material is constant
V＝πR2×L
M/πR2×L=m/πR2×Lo
L=M×Lo/m

The greatest common factor of two numbers is 4, and the least common multiple is 24. If one of them is 12, then the other is 12______ ．

Because 24 △ 4 = 6, 12 = 2 ×× 2 × 3, there are two cases of these two numbers: 4 × 1 = 4, 4 × 6 = 24 or 4 × 2 = 8, 4 × 3 = 12, so one of the numbers is 12, then the other is 8

Write two ratios equal to 13______ And______ And then they are proportioned______ ．

The ratio equal to 13 can be 1:3 and 2:6, and the composition ratio is 1:3 = 2:6

Write the proposition that the sum of two rational numbers is the inverse proposition of rational numbers, no proposition, no proposition

If the sum of two numbers is rational, then the two numbers are rational
The sum of two numbers that are not both rational numbers is not rational
If the sum of two numbers is not rational, then both numbers are not rational
