Which is bigger, 1 455 or 1 4545

First, the material introduction:

It is a martensitic precipitation hardening stainless steel developed on the basis of 630 steel, which has high lateral toughness and good malleability in addition to high strength, and the corrosion resistance is comparable to that of 630.

2. Applications and characteristics:

It is mainly used in service environments with high strength and good toughness and good corrosion resistance, such as high-strength forgings, high-pressure system valve parts, aircraft parts, etc.

If there is a rough omission in the title, it is like Yan Qi's words.

So, look for an ambush.

than large. Method 1: Directly observe this, the single digit is 1, and the decimal place is 5 than 4, so the ratio is larger.

Fa 2 Hengye: Shouting so greater.

To sum up, the ratio is large.

Compared with the larger front, you lack vertical observation, the integer is one, one decimal place, 5 is larger than 4, then the base is larger.

And which is the late bend big? Round.

Summary. With whom it is big.

Wait a minute.

Greater than greater than. So it's going to be greater than oh.

If there's anything you don't know, you can ask me again.

Summary. These two numbers are equally big. Because. Both are identical.

And which is bigger. These two numbers are equally big. Because. Both are identical.

Roger that. Question 1 is B because the score of the second is 1 8, that is, it is converted into a percentage.

Choose C for the second question. Reduced to 1% of the original.

Because adding a percent sign after it is equivalent to dividing by 100.

What kind of question? Four major questions.

Good. The germination rate from top to bottom is 96%, 97%, 92% and 95% respectively. 192÷200×100%=96%291÷300×100%=97%138÷150×100%=92%152÷160×100%=95%

Rice has the highest germination rate.

Soybeans have the lowest germination rate.

The germination rate of the seed should not exceed 100%. This is because the germination rate of seeds can only be 100% at most.

The number of germinations will not be greater than the total number of seeds.

Summary. Pro, than big. When comparing the size of two numbers, we can compare their integer parts and decimal parts.

In this case, the integer part of sum is 1, so we need to compare their decimal parts. The first decimal part is the decimal decimal place. In the middle, the tenth place is 4; And in the middle, the tenth place is 0.

Therefore, the decile is greater than the tenth. Since the deciles are the same, we need to continue to compare smaller digits. In the middle, the percentile is 6; And in the middle, the percentile is 0.

Therefore, the percentile is greater than the percentile. To sum up, greater than.

And who is big. And who is big.

Pro, than big. When comparing the size of two numbers, we can compare their integer parts and decimal parts. In this case, the integer part of sum is 1, so we need to compare their decimal parts.

The first decimal part is the decimal decimal place. In the middle, the tenth place is 4; And in the middle, the ten dresses are quietly divided into branches and filial piety 0. Therefore, the tenths are greater than the tenths.

Since the deciles are the same, we need to continue to compare smaller digits. In the middle, the percentile is 6; And in the middle, the percentile is 0. Therefore, the percentile is greater than the percentile.

To sum up, greater than.

In detail. When comparing the size of two numbers, we can compare their integer parts and decimal parts. In this case, the integer part of sum is 1, so we need to compare their decimal parts.

The first decimal part is the decimal decimal place. In the middle, if the remaining decile is 4; And in the middle, the tenth place is 0. Therefore, the decile is greater than the tenth.

Since the deciles are different, we can determine the greater than, because the value of the deciles determines the magnitude of the value. To sum up, the ratio is large.

Hello, to compare the size of two numbers, you can use the size symbol (>, random take, =) or subtraction. In this problem, we can use subtraction to compare and small and large keys. Specifically, we can calculate their differences, and if the difference is positive, it will be large; If the difference is negative, it is large; If the difference is 0, then they are equal.

Because the difference is positive, the ratio is large.

Therefore, the answer is big.

is greater because the integer part is the same, and 5 in the decimal part is greater than 4.

And is the absolute value of the large absolute value of the operation is 0544 then wide source.

Because of caution.
