Answer:
D. 8/15
Step-by-step explanation:
4/5 = 2/3 +1/3
We need to multiply by 6 to find answer as 3 is a divider of 6
4 x 6 =24
5 x 6 =30
24/30
Then we find 1/2 of 30 and add this to make 3/3
Just like 1/2 of 2 = 1 and 2+1 = 3
30 / 2 = 15
15 + 30 =45
The answer is 24/45
We then reduce this fraction by 3 as 6 + 8 do not divide into 45
24/45 = 8/15
The answer is 8/15
Its c (9) because the opposite of -9 is 9
