When you're subtracting negatives, you're adding them so... Here's a tip:
-9 - (-83)
So..
-9 + (-83) = -92
5*4/4 +1/4
20/4+1/4
21/4
You can multiply the whole number by 1, for the same number...but in the terms you need...for example, 5/5=1, but by multiplying by that, you'll get the number /5
X > 6
You can multiply each side of equation by the denominator to eliminate the fraction.
