Question

negative 9 over positive 4 + 3 over -7

Answer 1

The volume of 10,000 drops of a liquid is 100 fluid ounces.
What is the volume of 10 drops?

Answer 2

To simplify this expression, we first need to find a common denominator for both fractions. The common denominator for 4 and -7 is 28 (4*7=28).

Now we can rewrite the expression as:

(-9/4) + (3/-7)

To get rid of the denominators, we can multiply the numerator and denominator of each fraction by the denominator of the other fraction:

((-9)(-7) + (3)(4)) / (4 * -7)

Simplifying further:

(63 + 12) / -28
75 / -28

Finally, we have the simplified expression:

-75/28

Answer 3

To find the volume of 10 drops, we can set up a proportion using the given information:

Volume of 10,000 drops / Volume of 10 drops = Total volume / Volume of 10 drops

Plugging in the values we know:

100 fluid ounces / 10,000 drops = Total volume / 10 drops

Now we can solve for the total volume:

Total volume = (100 fluid ounces / 10,000 drops) * 10 drops

Simplifying:

Total volume = (100 / 10,000) * 10

Total volume = 0.01 * 10

Total volume = 0.1 fluid ounces

Therefore, the volume of 10 drops would be 0.1 fluid ounces.
