Question

Simplify: Negative four and one-fifth minus negative thirteen and one-tenth

Answer 1

\[-\frac{ 26 }{ 25 }\]

Answer 2

-4 1/5 - (-13 1/10) should be changed to
-21/5 - (-131/10), now seek a common denominator which is 10
-42/10 - (-131/10), now multiple trough by -1 to change the side of the second fraction
-42/10 + 131/10, and 131 - 42 = 89, so
89/10, which can also be written as 8 9/10
