Answer:

yes

Step-by-step explanation:

It depends on how accurate you want your answer to be, but basically yes, imagine we set our numerator to be x, and our denominator to be 2x, if we built our fraction we will get that:

\frac{x}{2x}=\frac{1}{2}

If the denominator of a fraction is exactly twice the numerator, then the fraction will be simplified to 1/2 or 0.5.

Now, the greater the denominator is, the closer the fraction will get to zero.

Take for example I had an fraction like this:

\frac{3}{6}=0.5

which approximates to 0. If we made the denominator bigger, let's say 7, we would get:

\frac{3}{7}=0.43

notice the answer is closer to 0 this time, so it's valid to round it to zero. If we made the denominator greater, let's say 25, we would get:

\frac{3}{25}=0.12

and so on. So it is true that if the denominator of a fraction is greater than twice the numerator, we can always replace the fraction with a 0 (depending on how accurate you want your answer to be).

9.) A new basketball is $10.95 and is 20% off. The sales tax is 7%.
blagie [28]

If you are trying to find the cost of the basket ball, it is $8.15.

Step 1: Find 20% of 10.95- which is 2.19- and subtract 2.19 from 10.95-which is 8.76.

Step 2: Find 7% of 8.76-which is 0.6132- and subtract 0.6132 from 8.76-which is 8.1468

Step 3: Round to the nearest hundredth, which gives you 8.15.

Thus, $8.15 is your answer.
