Help I will gave u brilliant answer please help​

Answer 1

so to add we need to find lcm

Explanation:

a) 5/8 + 1/2+3/4 lcm of 2,4 and 8 = 8

5/8 = 5/8

1x4
2x4 = = 4/8

3x2
4x2 = 6/8

5/8 + 4/8 + 6/8 = 15/8


b) 2/3 + 1/6 + 5/9 lcm of 3 , 6 and 9 = 18

2x6
3x6 = 12/18

1x3
6x3 = 3/18

5x2
9x2 = 10/18

12/18 + 3/18 + 10/18 = 25/18

Answer 2

a) 15/8 b) 25/18

Explanation:

a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator:
`(5+4+6)/(8) =(15)/(8)`

Since this can not be simplified any further, your final answer is 15/8.

b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same:
`(12+3+10)/(18) = (25)/(18)`

Since this cannot be simplified further either, your final answer is 25/18.

Hope this helps! :)
