What is -24 4/5 - 6 7/10?

Answer 1

To subtract mixed numbers, you need to convert them to improper fractions.

First, convert -24 4/5 to an improper fraction:
-24 4/5 = -(24*5 + 4)/5 = -124/5

Next, convert 6 7/10 to an improper fraction:
6 7/10 = (6*10 + 7)/10 = 67/10

Now, subtract the two fractions:
-124/5 - 67/10 = (-124*2)/(5*2) - 67/10 = -248/10 - 67/10 = (-248 - 67)/10 = -315/10

Finally, simplify the fraction if possible. Since both the numerator and denominator are divisible by 5, we can divide them both by 5:
-315/10 = -63/2

Therefore, -24 4/5 - 6 7/10 = -63/2.

Answer 2

or -24 4/5 - 6 7/10 = -24 8/10 - 6 7/10
= -30 15/10
= -31 5/10
= -31 1/2

Answer 3

Apologies for the mistake. You are correct.

-24 4/5 - 6 7/10 = -24 8/10 - 6 7/10
= -30 15/10
= -31 5/10
= -31 1/2

Answer 4

Our answers are the same. Just my way is easier.
