To subtract −24 4/5 from −6 7/10, we can write both numbers as improper fractions and then subtract them.
−24 4/5 = −(24*5 + 4)/5 = −(120 + 4)/5 = −124/5
−6 7/10 = −(6*10 + 7)/10 = −(60 + 7)/10 = −67/10
Now we can subtract:
−124/5 - (−67/10)
To simplify this expression, we need a common denominator. The least common multiple of 5 and 10 is 10. So, we'll multiply the numerator and denominator of the first fraction by 2.
−124/5 - (−67/10) = (−124 * 2)/(5 * 2) - (−67/10) = −248/10 + 67/10
Now that both fractions have the same denominator, we can subtract their numerators:
−248/10 + 67/10 = (−248 + 67)/10 = −181/10
Therefore, −24 4/5 - −6 7/10 = −181/10
−24 4/5−6 7/10
