1. 29/30
2.7/8
Explaination:
For number 1
Find the LCD of both fraction
6 - 12,18,24,30
10 - 20,30
LCD =30
4/6 (30÷6= 5×4=20) = 20/30
3/10 (30÷10=3×3=9)
Add the numerator
20 + 9 = 29
/30 /30 /30
for number 2
Find the LCD
8 - 16,24,32,40
2 -4,6,8,10
LCD = 8
3/8 (8÷8=1×3=3) = 3/8
1/2 (8÷2=4×1=4) = 4/8
3 + 4 = 7
