A beaker contains 1 1/4 pints of a chemical. A scientist pours the chemical out of the beaker until only 3 fluid ounces remain. How many fluid ounces of the chemical did the scientist pour out of the beaker? Enter your answer in the box.

Unit conversion is a way of converting common units into another. The fluid ounces of the chemical that the scientist poured out of the beaker is 22.

What is Units conversion?

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

As we know that 1 pint is equal to 20 fluid ounces, and as stated in the problem that the amount of chemical in the beaker is 1 1/4 pints, which can be written in fluid ounces as,

[tex]\text{Total chemical in beaker} = 1\frac14 \times 20 = \dfrac54 \times 20 = 25\rm\ fluid\ ounces[/tex]

Let the amount of chemical that is taken out of the beaker be x. It is described that the scientist pours the chemical out of the beaker until only 3 fluid ounces remain. Therefore, we can write,

Amount of chemical left = Total chemical in a beaker - The amount that is taken out of the beaker

[tex]\rm 3=25-x\\\\x=25-3\\\\x=22\ fluid\ ounces[/tex]

Thus, the fluid ounces of the chemical that the scientist poured out of the beaker is 22.
