If 3/5 of a number is 18, that means that 1/5 is 6 as 18/3 = 6. Since 1/5 is equal to 2/10. 1/10 of the number = 3. 7/10 of the number is 3*7 which is 21.
Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)
___________________
3x+5y=57
5x+5y=75
minus the equations top to bottom=
-2x= -18
x= -18/(-2)
x=9
He bought a total of 9 children tickets
The club was reduced by 225 people in all.
The answer would be
3 5/12, because you would make 3 2/3 into 3 8/12 for the greatest common factor and make 1/4 into 3/12 when you subtract 3/12 - 3 8/12 you get 3 5/12.
