4 and 2/3 minus 1 and 3/8 ... first make it an improper fraction. =
14/3 minus 11/8. Then find a common denominator. 3 * 8 = 24. 24 is the common denominator. 112/24 minus 88/24. 112-88 = 24 . 24/24 = 1 . that's the answer.
to divide fractions take the reciprocal(in other words flip the numerator and denominator for one fraction) of one fraction and multiply it by the other. To multiply fractions, multiply the two numerators to get the numerator and the two denominators to get the denominator.

4 2/3 - 1 3/8
= 14/3 - 11/8
= 79/24 ....... 1
(6 3/5 ) / (2 4/15)
= (33/5)/ (34/15)
= 13/3 .... 2
1/5 * 3/5
= 3/25..... 3
8 6/7 + 3 3/4
= 62/7 + 15/4
= (248 + 105)/ 28
= 353/28......4
Prime factors of 372 = 2*2*3*31
GCF of 372 & 110
372 = 2*2*3*31
110 = 2*5*11
GCF = 2
LCM 26& 65
26 = 2*13
65 = 5*13
LCM = 2*5*13 = 130

1) 8(14/3)-3(11/8)= 112/24-33/24= 79/24 can be converted into a mixed number
2) 33/5 * 15/34= 495/170 can be simplified further
3) = 3/5
4) 4(62/7) + 7(15/4) = 248/28+105/28= 353/28
