Answer:
-12 3/5
Step-by-step explanation:
-4 3/10 - 8 3/10
The signs are the same so we add and then take the sign
4 3/10 + 8 3/10
Add the whole numbers
4+8 = 12
Add the fractions
3/10 + 3/10 = 6/10
Simplify the fraction
6/10 = 3/5
Put them together
12 3/5
Add the sign
Change the mixed fraction to improper fraction
-4 3/10 = -43/10
-8 3/10 = -83/10
[tex]-4\frac{3}{10}-8\frac{3}{10}=\frac{-43}{10}-\frac{83}{10}\\\\=\frac{-43-83}{10}\\\\=\frac{-126}{10}\\\\=-12\frac{6}{10}[/tex]
