Answer:
 5/8
Step-by-step explanation:
Explanation:
First you need to put the same base for both numbers, finding the minimum common multiple of 4 and 8, that's 8.
Turning 1/4 in a number with 8 as base: first, divide 8 : 4 = 2. Then multiply 1/4 x2 and it will be 2/8.
Then you're able to calculate it: keep the base and add the tops
2/8 + 3/8 = 5/8

Chord AB = ?
Chord AB = AC + CB
Chord HI = HC + CI
HC = 7
CI = 28
Chord HI = 7 + 28 = 35
Chord AB = Chord HI
CB is 4 times the Length of AC. Let AC be X.
x + 4x = 35
5x = 35
x = 35/5
x = 7
AC = x = 7
CB = 4x = 4(7) = 28
