Question

PLEASE help me at 1 B !!!!

Answer 1

it would be 66 cause you know it

Answer 2

Answer:

a = 1, b = 4

Step-by-step explanation:

You have worked out part (a) correctly, that is

0.7575... = $\frac{75}{99}$ = $\frac{25}{33}$

(b)

$\frac{a}{11}$ + $\frac{b}{6}$ = $\frac{25}{33}$

$\frac{6a+11b}{66}$ = $\frac{25}{33}$  

Multiply numerator/ denominator of $\frac{25}{33}$ by 2, thus

$\frac{25(2)}{33(2)}$ = $\frac{50}{66}$ , then

$\frac{6a+11b}{66}$ = $\frac{50}{66}$ , thus

6a + 11b = 50

Choose a = 1 ( a positive integer ), then

6(1) + 11b = 50

6 + 11b = 50 ( subtract 6 from both sides )

11b = 44 ( divide both sides by 11 )

b = 4

a = 1, b = 4, so

$\frac{1}{11}$ + $\frac{4}{6}$ = $\frac{25}{33\\}$
