Answer:
15 boys and 20 girls
Step-by-step explanation:
1. Since we cant simplify 3:4 we will leave it just like that.
2. 3x+4x=35
3. We add them both to give us 7x=35
4. We divide by 7 to get x by itself which results in 35/7=5.
x=5
5. Now we found x we can create 2 seperate soulutions:
3(5)=
and 4(5)=
Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.

Answer: the first option is the correct answer.
Step-by-step explanation:
Martin runs 3/4 mile three days a week. We would assume that he runs a total of 3/4 miles in three days of each week.
In four weeks the number of days that he runs would be
3 × 4 = 12 days
Since he runs 3/4 miles in 3 days, the number of miles that he would run in 12 days would be
3/4 × 12 = 9 miles
He would run 9 miles in four weeks
