6 1/8 = 49/8
8x6=48+1=49
4 2/5 = 22/5
5x4=20+2=22
49/8+22/5
lowest common denominator=40
49x5=245/40
22x8=176/40
245+176= 421/40
421/40= 10.5 rounded down is 10
40x10= 400
421-400=21
10 21/40
whole number factors of 21- 1,3,7,21
whole number factors of 40- 1,2,4,5,8,10,20,40
HCF= 1
1(21)/1(40)
= 10 21/40
OR
6+4=10
1/8+2/5
5/40+16/40
=21/40
10 21/40
