Answer 1

а)15-16=15+(-16)=-1
б)-3⅛-0,125=-3,125-0,125=-3,125+(-0,125)=-3,25

Answer 2

a) To solve the equation 15 - 16, we can rewrite it as 15 + (-16). Adding a negative number is the same as subtracting, so we can calculate it as 15 - 16 = -1. The result of the equation 15 - 16 is -1.

b) To solve the equation -3⅛ - 0.125, we need to subtract 0.125 from -3⅛.

First, let's convert -3⅛ to a decimal. ⅛ is equal to 0.125, so -3⅛ is equal to -3 + 0.125 = -3.125.

Now we can subtract 0.125 from -3.125: -3.125 - 0.125 = -3.25. The result of the equation -3⅛ - 0.125 is -3.25.

Please let me know if there's anything else I can helpa) To solve the equation 15 - 16, we can rewrite it as 15 + (-16). Adding a negative number is the same as subtracting a positive number. So, 15 + (-16) equals -1.

b) To solve the equation -3⅛ - 0.125, we need to subtract 0.125 from -3⅛.

To subtract fractions, we need to have a common denominator. In this case, the common denominator is 8.

Converting -3⅛ to an improper fraction, we get -25/8.

Now, we can subtract 0.125 from -25/8.

To subtract fractions, we subtract the numerators and keep the denominator the same.

So, -25/8 - 0.125 equals -25/8 - 1/8, which equals -26/8.

Simplifying -26/8, we get -13/4.

Therefore, -3⅛ - 0.125 equals -13/4 or -3.25.
