Answer:

If we only use tenths, then we wont be able to model the hundredths place value that is the value of 4 in the given decimal.

Step-by-step explanation:

We are given the number 6.84

The place value chart for this number can be written as:

Place value:        Ones  .  Tenths  Hundredths

          6.84:             6     .       8               4

The decimal expansion can be written as:

6.84 = 6\times 1 + 8\times \displaystyle\frac{1}{10} + 4\times \displaystyle\frac{1}{100}

If we only use tenths, then we wont be able to model the hundredths place value that is the value of 4 in the given decimal.

To model 4 that is 0.04, we need

\displaystyle\frac{1}{10}\times \displaystyle\frac{1}{10}\times 4 = 0.04

To model 6, we need

10\times \displaystyle\frac{1}{10}\times 6 = 6

7 times as much as the sum of 1/3 and 4/5
Zanzabum
Well first we want to divide 1 by 3 , which is 0.3  ,  Now we need to divide 4 by 5 which is 0.8 . 

We have our answers but 7 needs to be added by their sum so lets put them together by adding them : 0.3 + 0.8 = 1.1.

Now lets add 7 and 1.1 all together , which is 8.1.

Answer:

x=c/a-b/a

Step-by-step explanation:

ax+b=c

1) Subtract b from both sides:

ax=c-b

2) Divide both sides by a:
