To write algebraic expressions
to model quantities is you base the algebraic expressions or mathematical
values declared in words by the manner of how the sentence illustrates the said
problem. For example, one minus a number is the difference of zero shall be
1.
1 – n = 0.
Other same examples, John bought 25 apples while Julia bought only
15 from the market. If Niccole bought twice as much as Julia’s, how many was
Niccole’s apples?

</span>You state
the problem by the sequence of the said problem and understanding the possible
structure.</span>

Julia = 15 apples
Niccole = 2Julia
Hence,
2Julia = 2(15) = 30 apples.
(2y + 5)° = 4y °
- 4y + 2y° = -5°
-2y° = -5°
y =5/2
The idea is to shift the number enough so that you can cancel the repeating digits by subtraction.
_____
Example
0.181818_18 multiplied by 100 gives
18.181818_18
Subtracting the original number gives
18.000000_00 . . . . . . all the repeating digits have been eliminated
When you multiply by 100 and subtract 1 times the original, you have multiplied by 99. Thus the value of the original number is 18/99 or 2/11.
