Let
One Number = x
Second Number =x-10
Third Number=x/2
Sum of three numbers is 50
x+x-10+x/2=50
2x-10+x/2=50
Multiply by 2 both sides
2*(2x-10+x/2)=50*2
4x-20+x=100
5x=100+20
5x=120
x=120/5
x=24
One number = x=24
Second number =x-10=24-10=14
Third number= x/2=24/2= 12
Answer:
Step-by-step explanation:
51:75
This is the same as 51/75.
Simplify by dividing 3 to the numerator and denominator:
17/25
Divide this to get a decimal:
17 / 25 = 0.68
Now multiply by 100 to get a percent:
0.68 * 100 = 68%
