You are trying to get the smallest number on top (numerator) and bottom (denominator). You divide the numerator and denominator by the same number.\n\nFor example, 180/240 can be simplified by dividing the numerator and denominator by 10 to get 18/24. Next you can divide the numerator and denominator by 6. 18 divided by 6 is 3, and 24 divided by 6 is 4 to get a simplified fraction of 3/4. \n\nThe trick is knowing which numbers divide the numerator and denominator evenly.

It is (-2)^2 * (2)^-2\nIt can be simplified as (-2)^2 / (2)^2\n= (-2)*(-2) / (2)*(2)\n= 4 / 4\n= 1\n\nSo the cotrrect answer is 1

Okay first of all you write it like this...\n(3.5-1.666~)/1.333~\nUsing fractions is easier in this case, so here it is.\n7/2-5/3= 21/6-10/6=11/6 division by a fraction is multiplication by the inverse, so multiply 11/6 by 3/4 and you get 33/24, which can be reduced to 11/8 (eleven-eigths)\n\nBy the way, it's spelled "parenthesis"

all you have to do is divide 4 by 9 = 0.444444

Use a division sign in parentheses. That way three fourths will look like (3/4).

7/5.\n\n(2/5)^2 = 4/25, then divide by (1/5) to get 4/5.\n\nAs for the rest, it's (-2) * (-3) / 10 = 6/10 = 3/5.\n\n3/5 + 4/5 = 7/5.

a/5 = 6\nYou want to isolate the 'a'.  Move the 5 from the left side of the equal sign to the other side of the equal sign.  When you move it to the other side you invert it, so 1/5 (a/5 is essentially a*1/5) becomes 5/1, or just 5, and multiply by whatever is on that side of the equal sign.  So you get:\na/5 = 6\na * 1/5 = 6\na = 6 * 5/1 \na = 6 * 5\na = 30

=[(-3)^2*12/9-1]/9=[12-1]/9=11/9\nand Brandy is also right (smile)

Ex. (6,2) \n\n6 times 5 over 2 times 1\n6 x 5/2 x 1= 30/10 = 3/1\n\nEx. (7,4)\n\n7 times 6 times 5 times 4 over 4 times 3 times 2 times 1\n7 x 6 x 5 x 4/4 x 3 x 2 x 1= 840/12=70\n\nGet it?
