Answer:

Step-by-step explanation:
1) Add 6 to both sides.

2) Simplify 21 + 6 to 27.

3) Divide both sides by 9.

4) Simplify 27/9 to 3.

The value decimal point is changing going to the right as you divide a number by 10.
For example
=> 2000.3 / 10
notice the decimal point
=> 200.013, the value of decimal numbers increases as the value of whole number decreases.Let’s divide again
=> 200.013 / 10
=> 20.0013 , now we already have 4 digits in our decimals.
So, simply as we divide the given number by 10, the decimal point moves to the left making the value of whole number decreases and making the number of digits of decimal increase.
Its I=prt
so plug it in
I=300(.06)3 i got .06 because you have 6% you have to move the decimal the left twice 0.06 is what you get
now its basic multiplying
300 times .06 times 3
so it would be 54
I=$54
the balence you get from adding the P to the I so the balence would be 356
Bal=$356
I think it's 1.90. I am not fully sure about the answer if it's wrong.
The answer would be 3/16 since 3*1 equals 3 and 4*4 equals 16
