Answer:To find the total amount, we need to find the value of one part of the ratio and multiply it by the sum of the ratio parts.Given ratio: Rio:Kim:Leo = 5:7:3Leo's share = 24,000Leo's ratio part = 3To find the value of one part:24,000 ÷ 3 = 8,000Now, multiply the value of one part by the sum of the ratio parts:Sum of ratio parts = 5 + 7 + 3 = 15Total amount = 8,000 × 15Total amount = 120,000So, the total amount is 120,000.
