How do you know the number of part to divide a number line from 0 to 1 into when comparing fractions
Katyanochek1 [597]
To compare fractions you need a common denominator, then you can make a comparison.  You would divide the number line between 0 and 1 (or any 2 whole numbers on the number line) based on that common denominator.  For example... if you were trying to compare 3/4 and 2/8, you would find the common denominator (in this case 8) and convert the fractions...

3/4 = 6/8
2/8 stays as 2/8

Now you would go to the number line between 0 and 1 and divide it into 8 equal pieces.  3/4 would go over the 6th division and 2/8 would go over the second division. 

That would give you a good visual that 2/8 < 3/4

0              2/8                               3/4               1

QUICK HELP!!!!
sasho [114]

Answer:

y =  \frac{3}{4} x -  \frac{3}{2}

Step-by-step explanation:

y =  \frac{3}{4} x - 1→y - y1 = m( x - x1)

y - 6 =  \frac{3}{4} (x - 6)→y - 6 =  \frac{3}{4} x - 6

2(y - 6) = 2( \frac{3}{4} )(x - 6)

2y - 6=  \frac{3}{2}( x - 6)

2y - 6 =  \frac{3}{2} x - 9

- 6 \: from \: both \: sides

2y  =  \frac{3}{2} x - 3

divede \: by \: 2 \: on \: both \: sides

y =  \frac{3}{4} x -  \frac{3}{2}

Hope this helps!

which do you think will have a greater value 1/8 of one pound of gold or 1/4 of one pound of lead?why
Inessa05 [86]
Well, if you multiply 1/8 by 4, the fraction become 4/32, and if you multiply 1/4 by 8 you get 8/32. Now that both fractions have the same denominator, we can determine which fraction is of greater value. Since the 1/4 or 8/32 of the one pound of lead has a greater numerator, it is of greater value.
