Answer:
23/63
Explanation:
1 and 2/3 can also be writen as 5/3
4 and 1/5 can also be written as 21/5
5/3 divided by 21/5 can be rewritten as 5/3 multiplied by 5/21
multiply the numerators (top numbers) for the numerator of the answer
5 x 5 = 25
multiply the denominators (bottom numbers) for the denominator of the answer
3 x 21 = 63
put the numerator and denominator together as the fraction 25/63
25 and 63 share no common factors, so the fraction cannot be further simplified
