If A:B = 5:18 and B:C = 6:4, form the ratio A:B:C

5 : 18 : 12

Step-by-step explanation:

Express the ratio B : C  in fractional form, that is

= ( cross- multiply )

6C = 4B ( divide both sides by 6 )

C = B = B , then

C = × 18 = 2 × 6 = 12

Hence

A : B : C = 5 : 18 : 12

5:18:12

Step-by-step explanation:

5:18

_:6:4 --> since you multiply 6 by 3 to get 18, multiply 4 by three to get the A:B:C ratio.

5:18:12

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
