Simplify negative 20๐ฅ over negative 10๐ฅ.
We can take negative 20๐ฅ over negative 10๐ฅ and break it into pieces. Our negative on the outside is representative of multiplying your fraction by negative one. Weโre going to multiply everything by negative one.
The numerator is saying 20 times ๐ฅ, and the denominator negative 10 times ๐ฅ. Letโs group the like terms even further. Negative one stays there. Then we can group 20 over negative 10 and multiply that by ๐ฅ times ๐ฅ. Hereโs what we have: negative one times 20 over negative 10 times ๐ฅ over ๐ฅ. We canโt simplify negative one any further yet, but 20 divided by negative 10 is equal to negative two. ๐ฅ divided by ๐ฅ equals one.
Any number, any value, over itself is a fraction of one. Negative one times negative two times one equals positive two. Negative 20๐ฅ over negative 10๐ฅ in its most simplified form is two.
