Draw as many rectangles as the whole number you are multiplying by. Then, draw the fraction you are multiplying by in all of the rectangles. Shade in the top number in the fraction [numerator] in your rectangles. Count all the shaded in parts of all your rectangles. Leave the bottom number of your fraction [denominator] the same and put the number you got when you added the shaded parts of the rectangles on top as your denominator of the fraction. That is your answer!

How can you use models to multiply fractions?
No, you cannot use models to multiply fractions!!
How do you make fractions easy?
Fractions aren't really difficult, once you understand them. Mainly, you have to memorize when to use which operation, so that you don't get adding and multiplying fractions confused, for example.
When do you use multiplying and dividing fractions in the real world?
You may not literally say "multiplied by a half" but multiplying and dividing by fractions are equivalents to doing the other function with an inverse number, most easily in that dividing by 2 is the same as multiplying by (1/2). We don't often multiply and divide by fractions because most of the time we can convert such a problem into a nicer one. We may use fractions like this, for example, in a test out of 90 marks where one must score 2/3 to pass. This pass mark is obtained by multiplying 90 by (2/3), though this, as said earlier, would usually, even unconsciously with such convenient numbers, be split into "divide by 3, then multiply by 2".
How do photographers use multiplying fractions in their everyday lives?
Photographers use that in their everyday lives because they have to make sure that the frame is correctly made and the picture is correctly cut.
What extra step will you have to perform if you do not use the least common denominator when adding fractions?
To add fractions, you have to find their common denominator by multiplying the two denominators together and one of the numerators to the others. Then you add just the top numbers together.
How you use the algorithm when multiplying fractions by fractions?
step by step

How can you use models to add fractions?
You can use models by doing simplify
Why do you not use common denominators while multiplying fractions?
probably to multiply easier

Why do you use mutiplication in math?
you use multiplication in math because somtimes you need it. like with fractions multiplying and adding are completely different
Who is making fraction multiplying worksheets?
If you are making just one multiplying fractions worksheet, I suggest going to multiplymath dot com. They have one off worksheets to use or you can create your own.
How do you multiply fractions with variables?
In order to multiply fractions with variables, factor all numerators and denominators completely. Use the rules for multiplying and dividing fractions, cancel any common factors, and leave your final answer in factored form.
What do the cells in a 144V hybrid battery look like?
Depends on the model. Most models use D-sized cells while some newer models use rectangular cells.

How can you use a rectangular model to help multiply fractions?
You don't need any complicated "model". Just multiply the top parts of both fractions and put the answer in the top part of the result. Similarly, the bottom part of the result is the product of the bottom parts of both fractions.
