Answer:
The answer is 11/59
Step-by-step explanation:
Given : (7/8 + (-15/25)) ÷ (7/8-(-15/25)) = ?
Solution : (7/8 + (-15/25)) ÷ (7/8-(-15/25))
= (7/8-15/25) ÷ (7/8 + 15/25)
LCM of 8 and 25 is 200
= (7x25-15x8)/200 ÷ (7x25-15x8)/200
= (175-120) /(175+120) ∵ 200 gets cancel in both
= 55/295
Divide both by 5, we get
= 11/59
