Comparision: Let say you buy chocolate that cost $1. And there was luckily a coupon, for 10% off.
That means after applying the coupon, you will only pay 90% of the original price. Which is
which equals 90 cents.
So let go back to this problem and apply similar thinking.
The price of the original root is g, so for the original price column, check the 3rd cell, g.
Use our comparision problem, by applying the coupon to the chocolate, you will save
which is 1/10 of the original price.
In this equation, we can represent this as 0.1g.
So for the second column, shade in 5th cell, 0.1g.
The price would be
So our equation for this equation will be
0.9g.
So for third column, shade in 1st cell, 0.9g.
Answer:
-----×1/72
Step-by-step explanation:
The <em>order of operations</em> says do these operations in order left to right. Please note that ÷ means the same as / unless you define it otherwise in your problem statement.
If you intend the ÷ symbol to be used to indicate everything to its left is divided by everything to its right, it is appropriate to use parentheses for that grouping, as in ...
(-----×1/4)÷(6×3/9) = (-----×1/4)÷2 = -----×1/8
_____
Here, we're going to evaluate what you have written according to the usual rules as described above.
(-----×1/4)÷6×3/9 = -----×1/24×3/9 = -----×(3/24)/9
= -----×1/8/9
= -----×1/72
_____
<em>Comment on the arithmetic</em>
Fractions are multiplied and divided in the usual way:
a/b×c = (a×c)/b
a/b/c = (a/b) × (1/c) = a/(b×c)
___
<em>Comment on fractions and parentheses</em>
Please note that parentheses are required on any numerator or denominator that consists of anything other than a single number or variable. (The exception is the case where the numerator is a product, because a·b/c = (a·b)/c with or without the parentheses.)
