Answer:
[tex]21\frac{1}{3} /\frac{64}{3}[/tex]
Step-by-step explanation:
In order to find the answer to this question you need to remember that all numbers have a invisible denominator that comes into effect when you are doing anything with fractions that invisible denominator is 1, and of course remember KCF (Keep, Change, Flip) while solving this problem.
[tex]20\div\frac{15}{16}[/tex]
[tex]20=\frac{20}{1}[/tex]
[tex]\frac{20}{1} \div\frac{15}{16}[/tex]
Use KCF:
[tex]\frac{20}{1} \times\frac{16}{15}[/tex]
Multiply:
[tex]20\times16=320[/tex]
[tex]1\times15=15[/tex]
[tex]=\frac{320}{15}[/tex]
Simplify:
[tex]320\div5=64[/tex]
[tex]15\div5=3[/tex]
[tex]=\frac{64}{3}[/tex]
Convert into mixed number:
[tex]64\div3=21.33333=21[/tex]
[tex]64-(3\times21)=1[/tex]
[tex]=21\frac{1}{3}/\frac{64}{3}[/tex]
Hope this helps.
