Answer:
4/3 is the number she thought of
Step-by-step explanation:
Let the number she thought be 'x'
She subtracted 5/6 from x
so the answer is x-(5/6)
Multiply the result by 8
8 (x-(5/6))
=8x-8*(5/6)
=8x-(20/3)
The answer is 3 times x
Make an equation...
8x-(20/3)=3x
8x-3x=20/3
5x=20/3
x=(20/3)*1/5
x=4/3
Confirmation...
8 ((4/3)-(5/6))=3*(4/3)
8 ((8-5)/6)=4
8 (3/6)=4
8*1/2=4
8/2=4
Hope it helps......
