Answer 2
Answer:

Final answer:

There are 420 students divided into 7 parts due to the ratio of girls to boys being 4:3. With one part totaling 60 students, there are 240 girls and 180 boys. Thus, there are 60 more girls than boys.

Explanation:

To solve this problem, you need to understand the concept of ratios. In this case, the ratio of girls to boys is 4:3. This means that for every 4 girls, there are 3 boys. If we add the two parts of the ratio together, we get 7 parts. This means that the total number of students, which is 420, is to be divided into 7 parts.

So, one part of this ratio is equal to 420 divided by 7, which equals 60 students. Since the ratio claims there are 4 parts of girls and 3 parts of boys, to find out the numbers of girls and boys, we multiply each part of the ratio by 60. Hence, the total number of girls is 4 multiplied by 60, which equals 240 and the number of boys is 3 multiplied by 60, which equals 180.

Therefore, the difference in number between girls and boys is 240 minus 180, which equals 60. So there are 60 more girls than boys.

Explain why Six less than three times a number is 21. Find the number.

Answers

Answer: 9

Step-by-step explanation: The reason that students get intimidated

by word problems is they try to look at all the information at once.

The best way to approach a word problem

is to break it down sentence by sentence.

In this problem, let's look at the first part of the sentence.

We know that six less than three times a number is 21.

Let's call the number x.

So we know that six less than three times a number means 3x - 6.

A common mistake would be for students to put 6 -  3x.

However, the word "less than" switches the order around.

So we know that six less than three times a number is 21.

So we can write this as 3x - 6 = 21.

Now we have an equation and we can solve for x.

First add 6 to both sides to get 3x = 27.

Now divide both sides by 3 to get x = 9.

So our answer to this word problem is 9.

Answer:

2000

Step-by-step explanation:

If 3 days = 600 we need to know what 1 day is so we do 600 / 3

600 / 3 = 200

Then multiply 200 by 10 to find 10 days

200 * 10 = 2000

10 days = 2000

Let’s see 1,2,3,4,5,6,7,8,9
We have to identify our evens from our odds
2,4,6,8 are evens
1,3,5,7,9 are odds.
From this we can conclude there are 4 even numbers so that is a 4/9 chance to pick an even or 44% chance.
