Two numbers are in ratio 5: 3,if the differ by 18 what are the numbers

45

27

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

5/3 = x/y

The numbers differ by 18

x - y = 18                      Add y to both sides

x = 18 + y                      Substitute for x in the ratio

5/3 = (18 + y)/y             Cross multiply

5y = 3(18 + y)               Remove the brackets

5y = 54 + 3y                Subtract 3y from both sides

5y - 3y = 54 + 3y-3y    Combine

2y = 54                        Divide by 2

2y/2 = 54/2    

y = 27

The smaller number is 27

x = y + 18

x = 27 + 18

x = 45

The larger number is 45

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
