What is a common denominator for 5/12 and 2/9
hram777 [196]

because the denominator is on the bottom, you have to find a number which both 12 and 9 can be divided by. In this case the only answer that isn't a decimal is 3

A packing crate can hold 205 avocados. There were 7000 avocados picked at a large grove. The owner has 36 packing crates. Does h
larisa [96]
First, you would have to divide 7000 by 205. This gives you 34 & a remainder. The owner can't pack parts of a crate so yes he does because he only has 34 full crates to ship. Leaving him with 2 extra crates left.

Write a division problem that will have a 2 digit quotient and another division problem that will have a 3 digit quotient. Expla
o-na [289]

Answer:

\frac{240}{4} =60

\frac{1800}{3} =600

Step-by-step explanation:

1.  The result should by a 2 digit number.

So, I fix a two digit number first, say 60.

Then, I multiplied it by some random integer, say 4 and got 240.

Now, 240 is my dividend and 4 is my divisor.

My division problem is:

\frac{240}{4} =60


2.  The result should be a 3 digit number.

So, I fix a three digit number first, say 600.

Then, I multiplied it by some random integer, say 3 and got 1800.

Now, 1800 is my dividend and 3 is my divisor.

My division problem is:

\frac{1800}{3} =600

The sum of the reciprocals of two consecutive even integers is 7/24. Write an equation that can be used to find the two integers
sergejj [24]
Assume the first even integer is x.
The next even integer will be 2 digits after this digit. So the next even integer will be x+2.

The reciprocals of these two even integers can be written as \frac{1}{x} and \frac{1}{x+2} respectively.

The sum of their reciprocals is 7/24. So we can set up the equation as:

\frac{1}{x}+ \frac{1}{x+2}= \frac{7}{24}

Taking LCM on left hand side:

\frac{x+2+x}{x(x+2)}= \frac{7}{24} \\  \\ 
 \frac{2x+2}{ x^{2} +2x}= \frac{7}{24}

Cross Multiplying the denominators:

24(2x+2)=7({ x^{2} +2x}) \\  \\ 
48x+48=7 x^{2} +14x \\  \\ 
7 x^{2} +14x-48x-48=0 \\  \\ 
7 x^{2} -34x-48=0 \\  \\ 



Using the quadratic formula to solve the above equation:
7 x^{2} -34x-48=0 \\  \\ 
x= \frac{34+- \sqrt{1156+1344} }{14} \\  \\ 
x= \frac{34+- \sqrt{2500} }{14} \\  \\ 
x=\frac{34+-50 }{14} \\  \\ 
x=6 \\ x=- \frac{8}{7} 


Since, the value of x can only be an integer, we discard the fractional value and keep x=6

So the first even integer is 6 and the next even integer is 8. The sum of reciprocals of 6 and 8 is 7/24
