Answer 2

SOLUTION

TO DETERMINE

The number in the blanks 7 : 8 : 9 = __ : 12 : __

EVALUATION

Let the numbers in the blanks be a and b

So that 7 : 8 : 9 = a : 12 : b

Now 7 : 8 = a : 12 gives

$\displaystyle \sf{} \frac{7}{8} = \frac{a}{12}$

$\implies \sf{} \displaystyle \sf{} 8a = 84$

$\implies \displaystyle \sf{} a = \frac{84}{8}$

$\implies \displaystyle \sf{} a = 10.5$

Again

8 : 9 = 12 : b gives

$\displaystyle \sf{} \frac{8}{9} = \frac{12}{b}$

$\implies \displaystyle \sf{} 8b= 108$

$\implies \displaystyle \sf{} b = \frac{108}{8}$

$\implies \displaystyle \sf{} b = 13.5$

FINAL ANSWER

$\boxed{ \sf{} \: 7 : 8 : 9\: = 10.5 \: : \: 12 \: : \: 13.5 \: }$
