Question

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

Answer 1

(-4 and 1/5) - (-13 and 1/10)

change the denominator to be the same, what times 5 is 10
multiply by 2 to get 1/5 equals 2/10 and 1/10 stays the same
new equation -4 and 2/10 - -13 and 1/10
-4 - (-13), negative minus a negative equals a positive
solve to get 9
2/10 - 1/10 = 1/10

so simplified answer is 9 and 1/10
