Answer:
£30
Step-by-step explanation:
To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.
1 : 6 = 1 + 6 = 7 parts
Now divide the total amount of parts by the total amount of money shared
35 / 7 = 5
Now multiply the answer by the value that is appropriate.
In this case, they want you to work out how much Ali recieved.
Ali's value is 6
6 × 5 = £30
hope this helps :)
<span>In order to determine the value of the numbers, we can set up algebraic equations to solve. For this case, we need to set up two equations since we have two unknown numbers. We do as follows:
let x = first number and y = second number
From the problem statement, we set up equations.
Equation 1 - the numbers have a difference of 0.7
x - y = 0.7
Equation 2 - the numbers have a sum of 1
x + y = 1
Solving for x and y via substitution method,
x - y = 0.7
(1-y) - y = 0.7
1 - 2y = 0.7
-2y = 0.7 - 1 = -0.3
y = 0.15 or 3/20
x - 0.15 = 0.7
x = 0.85 or 17/20
Thus, the two numbers are 0.15 and 0.85.</span>
Composite numbers are numbers that have the same set of factors
