<em><u>Answer</u></em>

In order to use the distributive property I first get the amount of the water fell in ;

<u>One </u><u>year</u>

1.68mm

<u>A </u><u>half</u><u> </u><u>a </u><u>year</u>

½× 1.68mm

= 0.84mm

<u>One </u><u>and </u><u>a </u><u>half </u><u>years (</u><u>Using </u><u>the</u><u> </u><u>distributive</u><u> </u><u>property</u><u>)</u>

1.68mm + 0.84mm

<u>1</u><u>6</u><u>8</u><u>m</u><u>m</u> + <u>8</u><u>4</u><u>m</u><u>m</u>

100. 100

(168÷100) + (84÷100)

(168+84) ÷ 100

252 ÷ 100

<u>2</u><u>5</u><u>2</u>

100

= 2.52mm

Therefore the variation in the water level in the time period was 2.25mm

And in doing so, you'd start your first step to having "like terms" on "like sides"
by having all "x's" on the right side of your equivalent sign "="

From 95 to 68 percent decrease
Kay [80]

The decrease is  (95-68) = 27 .

As a fraction, the decrease is  27/95  of the original amount.

To change any fraction to a decimal, do the division:

                             (27)  divided by  (95) = 0.2842...

To change any decimal to a percentage, move the
decimal point two places that ==> way:

                             0.2842...  =  28.42... %
