Answer:
No. of boys = 15
Step-by-step explanation:
Given that,
The ratio of boys to student is 3:7.
Number of girls in the school = 20
We need to find the number of boys in the school.
Let there are 3x boys and 7x number of students.
No. of girls = Total students - no. of boys
= 7x-3x
= 4x
ATQ,
4x = 20
x = 5
No. of boys = 3x
= 3(5)
= 15
Hence, there are 15 boys in the school.
Hey!
Dean's family has been traveling on the same speed for two days, so to find how far you will need to travel you will need to find how far they are traveling in one hour..
To find this you will need to set up a proportion...
3/195 = 1/x
Solve this proportion by cross multiplying and then dividing..
195 * 1 = 195/3 = 65
This tells you that they are traveling 65 miles per hour. Now with this you will simply have to multiply 65 by 5 to tell you how far they would be traveling in 5 hours with the given speed...
65 * 5 = 325
Your answer of 325 miles tells you how far they traveled.
Hope it Helped!
