Ida is cutting a 11/12 foot wooden board into 3/16 foot sections to do some detail work on a model she is building. How many whole 3/16 foot sections are there in the 11/12 foot wooden board? Explain your answer and show your work.

you have to give them the same denominator so multiply 11/12 by 4 and 3/16 by 3. giving you 44/48 and 9/48. then divied 44 by 9 giving you 4.8888
there for there are 4 whole 3/16 sections of the 11/12 board

Answer:

4

Step-by-step explanation:

We have to perform the division:

[tex]\displaystyle\frac{11}{12}\div\frac{3}{16}[/tex]

We turn it into a multiplication of the first fractions times the reciprocal of the second fraction:

[tex]\displaystyle\frac{11}{12}\cdot\frac{16}{3}[/tex]

We can simplify the 16 on top with the 12 on bottom by dividing them by the common divisor 4, to get:

[tex]\displaystyle\frac{11}{3}\cdot\frac{4}{3}[/tex]

Then we perform the multiplication:

[tex]\displaystyle\frac{44}{9}[/tex]

We then divide 44 by 9 to get quotient 4 and remainder 8.

So we can write the result as the following mixed number:

[tex]4\displaystyle\frac{8}{9}[/tex]

We are only asked for the whole part, which is 4. It means there are 4 whole 3/16 foot sections in the 11/12 foot wooden board.
