Answer:

130 milliliters.

Step-by-step explanation:

a drug has a ratio of 115mg:5ml. This is equivalent to 23mg:1ml. 3g=3000mg, so we divide 3000 by 23 to get 130.434783. That is how many milliliters are needed. We round it to get 130 mL.

Answer: \dfrac{53}{16}\ \text{or}\ 3\dfrac{5}{16}

Here goes another question: 4/5%9/10 and please if you can with procces
love history [14]
When you divide a fraction by another fraction, it is the same thing as multiplying that fraction by its reciprocal.

The reciprocal is the 'flipped' version of a fraction where the numerator becomes the denominator and the denominator becomes the numerator.

for example, the reciprocal of 9/10 is 10/9

Knowing this information 4/5÷9/10 is the same as 4/5×10/9

Now we can solve...

\frac{4}{5} * \frac{10}{9} = \frac{40}{45} = \frac{8}{9}

Answer= 8/9
