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 diviedĀ 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:
\(\displaystyle\frac{11}{12}\div\frac{3}{16}\)
We turn it into a multiplication of the first fractions times the reciprocal of the second fraction:
\(\displaystyle\frac{11}{12}\cdot\frac{16}{3}\)
We can simplify the 16 on top with the 12 on bottom by dividing them by the common divisor 4, to get:
\(\displaystyle\frac{11}{3}\cdot\frac{4}{3}\)
Then we perform the multiplication:
\(\displaystyle\frac{44}{9}\)
We then divide 44 by 9 to get quotient 4 and remainder 8.
So we can write the result as the following mixed number:
\(4\displaystyle\frac{8}{9}\)
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.
