Answer:

Step-by-step explanation:

By Basic proportionality theorem:

$\frac{10}{8} = \frac{3x - 6}{12} \\ \\ \frac{10 \times 12}{8} = 3x - 6 \\ \\ \frac{120}{8} = 3x - 6 \\ \\ 15 = 3x - 6 \\ 15 + 6 = 3x \\ 21 = 3x \\ \frac{21}{3} = x \\ 7 = x \\ \\ \huge \red { \boxed{x = 7}}$

Angelina_Jolie [31]

The total number of cookies baked by grandma = 96

Number of grandchildren = 8

As given, all cookies were evenly divided among 8 children, let us assume that everyone except Cindy got equal share. So on being divided equally, it becomes, $\frac{96}{8}=12$ cookies per children.

But, as mentioned that Cindy received 'c' cookies less, so let us suppose Cindy received 'x' cookies.

Expression becomes: $x=12-c$

Hence, Cindy received 12-c cookies.

The change from 3/4 to 4/10 is found by obtaining and applying the LCD:

15/20 to 8/20 is a negative change, and the amount of the change was -7/20.

We compare this result to the original value, 15/20, to obtain the percentage change in the fraction:

-7/20
----------- = -7/15 = -0.467 => -46.7%
