Step-by-step explanation:
1. 6 1/3 + 4 1/6
= 19/3 + 25/6
= 19×2/3×2 + 25/6 (LCM of 3 and 6 is 6)
= 38/6 + 25/6
=63/6
=10 3/6
2. 7 2/5 + 3 1/10
= 37/5 + 31/10
= 37×2/5×2 + 31/10 (LCM of 5 and 10 is 10)
=74/10 + 31/10
=105/10
= 10 5/10
3. 10 1/4 + 8⅗
= 41/4 + 43/5
= 41×5/4×5 + 43×4/5×4 (LCM if 4 and 5 is 20)
= 205/20 + 172/20
= 377/20
= 11 3/20
4. 7⅗ + 9 2/7
= 38/5 + 83/7
= 38×7/5×7 + 83×5/7×5 (LCM of 7 and 5 is 35)
= 266/35 + 415/35
= 681/35
= 19 16/35
