A. 11/15
B. 4/15
C. 12/15
D. 8/15

Answer 1

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
