Question

Which values of a, b, and c represent the answer in simplest form? StartFraction 7 Over 9 EndFraction divided by StartFraction 4 Over 9 EndFraction = a StartFraction b Over c EndFraction a = 1, b = 4, c = 3 a = 1, b = 3, c = 4 a = 1, b = 63, c = 36 a = 1, b = 36, c = 63

Answer 1

Answer:

(A) is the correct answer

Step-by-step explanation:

1/6 stays the same but 3/5 canges to 5/3                                                                                                      

Answer 2

Answer:

Option 2 - a=1, b=3 and c=4

Step-by-step explanation:

Given : Expression  $\frac{7}{9}\div\frac{4}{9}=a\frac{b}{c}$

To find : Which values of a, b, and c represent the answer in simplest form ?

Solution :

Solving the expression first and then convert into mixed fraction.

$\dfrac{7}{9}\div\dfrac{4}{9}=\dfrac{\frac{7}{9}}{\frac{4}{9}}$

$\dfrac{7}{9}\div\dfrac{4}{9}=\dfrac{7\times 9}{9\times 4}$

$\dfrac{7}{9}\div\dfrac{4}{9}=\dfrac{7}{4}$

Writing $\frac{7}{4}$ into mixed fraction by dividing the number,

$\dfrac{7}{9}\div\dfrac{4}{9}=1\dfrac{3}{4}$

On comparing, a=1, b=3 and c=4.

Therefore, option 2 is correct.
