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.

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

HURRY!!!!!!!!!<br><br> Given P(5,10,8) and Q(7,11,10), find the midpoint of the segment PQ.
rusak2 [61]

Answer:

P_{m}=(6,10.5,9)

Step-by-step explanation:

The mid point can be found with the formula

P_{m}=(\frac{x_{1}+x_{2} }{2},\frac{y_{1} +y_{2} }{2} ,\frac{z_{1}+z_{2}  }{2} )

The given coordinates are P(5,10,8) and Q(7,11,10).

Replacing coordinates in the formula, we have

P_{m}=(\frac{5+7}{2},\frac{10+11 }{2} ,\frac{8+10}{2} )=(\frac{12}{2},\frac{21 }{2} ,\frac{18}{2} )\\P_{m}=(6,10.5,9)

Therefore, the mid point of the segment PQ is P_{m}=(6,10.5,9)

ELEN [110]

your total would be $10 and you have 1 variable. so it would be ($2x) for the pounds of veggies, plus the 3.50 for the basket, equals $10. then solve for X from there

5/7 ............. 15/21<br><br> NONE OF THESE<br> EQUAL<br> GREATER THAN<br> LESS THAN
sertanlavr [38]

Answer: EQUAL

Step-by-step explanation:

Just as you can do the same thing to both sides of an equation, you can do the same thing to both sides of a fraction.  15 = 5*3 and 21 = 7*3.  Thus, 5/7=15/21

Hope it helps <3 :)
