Final answer:
To find the total amount of money that Joshua, Amira, and Salah shared, we need more information.
Step-by-step explanation:
To find the total amount of money that Joshua, Amira, and Salah shared, we need to use the given ratio and the information that Amira received £940 less than Joshua.
Let's start by assigning a value to the ratio. We can choose a value that is easy to work with, such as 4, 2, and 7.
Since Amira received £940 less than Joshua, we can subtract £940 from Joshua's share. Let's call Joshua's share 'x'. Amira's share would be 'x - £940'. Salah's share would be '7x'.
Adding up the amounts, we get:
Total = x + (x - £940) + 7x
Simplifying the expression:
Total = 9x - £940
To find the value of 'x', we need more information. Unfortunately, we cannot determine the exact amount of money they shared without additional details.
