i dont understand what ur saying Aziz!what are the three points!?

are there three problems in this or just one?

but we arent adults right!so it would be good if u dont be rude!

and for your hint, i cant find any use of it!it like a nursery school rhyme!

i think to turn a decimal into a fraction we would do like this

lets assume 231.45 as a decimal number we r to turn to fraction!

so as there are two numbers behind the decimal point we'd divide it by 100 and if there would be 3 numbers after the decimal point then by 1000 and so the zeroes increase like this!

and now lets do it

231.45 = 23145/100   

and so we have turned the decimal into fraction!

and if u reduce it u will have 4629/20 

So lets try this

suppose -9 and -8 are two negative numbers and we are adding them

(-9)+(-8)        (now we would change the minus sign of 8 and that addition sign to addition sign becoz a negative and a positive means a positive sign)

= -9 + 8    (and now simply subtract them)

= -1 ANSWER

so yeah as ReptyGT said it depends on what your adding!what are the numbers!

Wow!thats so nice DS!i'd give u a point for that!

i think u should just ignore him!and pls dont put the crying smiley that doesnt suit on u!ur smiley looks nice if its smiling!

So we'd solve this like

-3(x-3)= -9   (now out here we will first multiply -3 by x and -3 )

-3x - 9 = - 9         (and now we will take -9 to the other side with -9 to put like terms together)

-3x = -9 -9          ( and now we would add the two -9's and also put the minus sign)

-3x = -18           (now we will take -3 to the other side and divide it by -18 which will then give us our x and also we will cut the two minus signs while dividing the two)

x = -18 / -3         (now simply divide)

x = 6      ANSWER

i hope uve understood by now but if not then pls be free to ask!

hope this helps!

Anonymous is it right that im feeling that your being a lil rude to DS!

u may use the on site calc as well!
