Question

Answer 1

hope this help..........................

Answer 2

5a = 13b = 7c

Express a in term of b:

5a = 13 b

a = 13/5 b

Express c in term of b:

7c = 13b

c = 13/7 b

Express the ratio of a : b : c in term of bs:

a : b : c = 13/5 b : b : 13/7 b

divide by b through:

a : b : c = 13/5 : 1 : 13/7

Multiply by 35:

a : b : c = 19 : 35 : 65

Answer: The ratio is 19 : 35 : 65
