Answer:
first number=14.9,second number=89.4 and third number=8.9
Step-by-step explanation:
let the first number be "a" , second number be "b" and third number be "c"
From the question above we know,
b=6a
c=a-6
And b+c=98
so we can write,
b+c=98
(6a)+(a-6)=98
6a+a=98+6
7a=104
a=104/7
∴a=14.9(correct to 3 sig. fig.)
again
b=6a=6(14.9)= 89.4(correct to 3 sig. fig.)
c=a-6=(14.9)-6=8.9(correct to 3 sig. fig.)
Now if u want to make sure that ur answer is correct just add b+c and see if its 98
b+c=98
89.4+8.9=98.3=98(correct to whole number)
