use a diagram to show an equivalent fraction to 3/4

Question

i love math but i need help please help me with my questions

Answer 1

I can't draw in the text program but I will do my best to describe what one might look like.

 

Draw a rectangle with lines in it that divide it into 4 equal pieces.  You can do this by drawing 3 vertical (straight up and down) lines or with 2 lines that cross each other to make a + sign.

 

Lightly shade in 3 of the 4 equal sized pieces.

 

Draw the same rectangle again with dividing lines and shading but when you are finished draw more lines to divide each of the four pieces into halves making a total of eight equal pieces or into thirds making 12 total pieces or...

 

Once you finish count the total number of pieces made and the number that is shaded.  Use these numbers to make your equivalent fraction. 

 

shaded pieces/total number of pieces

 

in the end you should be able to say that 3/4=?/? from your newly divided rectangle

Answer 2

One of the easiest ones would be to have a rectangle and cut it up lengthwise into four pieces. Fill/shade in three of those. That represents ³/₄. (the figure may be a little off due to lack of preview, but the gist should make sense):

 

--------------------------------------

|xxxxx|xxxxx|xxxxx|       |

|xxxxx|xxxxx|xxxxx|       |

|xxxxx|xxxxx|xxxxx|       |

|xxxxx|xxxxx|xxxxx|       |

--------------------------------------

 

Now you can cut it in the other direction:

--------------------------------------
|xxxxx|xxxxx|xxxxx|       |
|xxxxx|xxxxx|xxxxx|       |

--------------------------------------

|xxxxx|xxxxx|xxxxx|       |
|xxxxx|xxxxx|xxxxx|       |
--------------------------------------

 

And now you'd have an equivalent fraction of ⁶/₈.
