To find which expression is equivalent to (9 div 0.3), we can simplify (9 div 0.3) first.
We can rewrite the division as follows:
[
9 div 0.3 = 9 div frac{3}{10} = 9 times frac{10}{3} = frac{90}{3}
]
This means that:
[
9 div 0.3 = 90 div 3
]
So, the correct answer is (90 div 3).
This works because dividing by a fraction is the same as multiplying by its reciprocal, which in this case allows us to simply switch (0.3) into a more manageable fraction.
