Answer:
The first number is
72.6
Step-by-step explanation:
Let second number be x.
First number= 6x
Third number= 3x
According to question,
6x+x+3x=121
or, 10x=121
or,x=121/10=12.1
First number= 6x=6×12.1=72.6
Third number=3x=3×12.1=36.3
Turn the percentage into a decimal
30% = 0.3
Multiply.
80 * 0.3 = 24
Best of Luck!
