First put them into improper fractions which are 77/19 and 31/21, then multiply 77 and 31 and get 2387, and multiply the denominators 19 and 21 which is 399. Then u can put it into a simplified fraction of u wnat

The answer is 5 [tex] \frac{56}{57} [/tex]. 1.)Transform the  mixed numbers into proper fractions. 4 [tex] \frac{1}{19} [/tex] = 19x4 = 76+1=77=[tex] \frac{77}{19} [/tex]. 1 [tex] \frac{10}{21} [/tex] = 21x1=21+10=31= [tex] \frac{31}{21} [/tex].
2.) Multiplying two fractions. [tex] \frac{77}{19} [/tex] x [tex] \frac{31}{21} [/tex]=[tex] \frac{2387}{399} [/tex]. 3.) Simplifying a fraction. [tex] \frac{2387}{399} [/tex] = [tex] \frac{341}{57} [/tex]. 4.) Since the numerator greater then the denominator, convert the improper fraction to mixed number. [tex] \frac{341}{57} [/tex] = 56+5x57/57 = 5 [tex] \frac{56}{57} [/tex]
