Answer:

240: 180

Step-by-step explanation:

total part 4+3=7

7 part =420

1 part =60

4 part=240

3part=180

Answer 2

Answer:

8th graders = 240

7th graders = 180

Step-by-step explanation:

So let no. of children be x then according to the ratio of 8th graders to 7th graders

8th graders = 4x and 7th graders = 3x

Now lets see the equation for this question

4x + 3x = 420

7x = 420

x = 420/7

x = 60

So 8th graders = 60*4 = 240

and 7th graders = 60*3 = 180
