Answer 1

Answer:

6:7:8

Step-by-step explanation:

Let 6a=7b=8C=K

6a=k

a=k/6

7b=k

b=k/7

8c=k

c=k/8

k/6:K/7:k/8

=6:7:8

Answer 2

Answer:

28:24:21

Step-by-step explanation:

First we need to convert all the values to one particular variable.

here I am expressing the values of a and c in terms of b.

then

a=

$a = \frac{7b}{6} \\ c = \frac{7b}{8} \\ now \: according \: to \: the \: question \:$

a:b:c=

$\frac{7b}{6} \div b \div \frac{7b}{8} \\ \\ = \frac{7}{6} \div \frac{1}{1} \div \frac{7}{8} \\ = \frac{28}{24} \div \frac{24}{24} \div \frac{21}{24} \\ = 28 \div 24 \div 21$

hope it helps
