Answer 1

Answer:

9.333

Step-by-step explanation:

$19. \: cross \: multiplying \\ 6a = 7 \times 8 \\ 6a = 56 \\ \frac{6a}{6} = \frac{56}{6 } \\ a =9.333$

25. Cross multiplying

nx1 =0.19x12

n=2.28

Answer 2

Answer:

$\Large \boxed{{19. \ a \approx 9.33}} \\ \\ \Large \boxed{25. \ n=2.28}$

Step-by-step explanation:

(19)

$\displaystyle \frac{6}{8} =\frac{7}{a}$

Cross multiply.

$(6)(a)= (7)(8)$

$6a=56$

Divide both sides by 6.

$\displaystyle a = \frac{56}{6}=\frac{28}{3}$

$a \approx 9.33$

(25)

$\displaystyle \frac{1}{0.19} =\frac{12}{n}$

Cross multiply.

$(1)(n)=(0.19)(12)$

$n=2.28$
