1. Strategy I would use
Let me show you an strategy:
<u>Break apart strategy:</u>
The strategy of break apart numbers (Place Value) consists in the decomposition or separation of numbers. We can break both numbers down to place value and add each, starting with the largest or keep one number intact and only break second number down by place value and adding each place. Anyway, using this strategy we have:
2 + 8 = ?
2 breaks into 1 plus 1 (1 + 1), 8 breaks into 4 plus 4 (4 + 4), so by associative property:
(1+4)+(1+4) = 5+5=10
2. Explain how I decided.
This strategy is good to add larger numbers. In this way, we may break larger numbers up into hundreds, tens, ones, then add. This is an easy way to find additions.
I believe the answer would be 8, because dividing the area by the width would give us the length, so 24/3=8
Answer: The third answer
Step-by-step explanation:
7/10 is 0.7 and 2/6 is 0.33, 2/6 would be less than 1/2 because 1/2 is 0.5, 0.7 is greater than that benchmark
You have:
<span>Cost in dollars --> $2.89 </span>
<span>Total ounces --> 4.25 </span>
<span>But you want to know the per unit cost for *1* ounce. </span>
<span>You have the right method. You want cost ($) per ounce so put the price over the amount in ounces. </span>
<span>2.89 / 4.25 = x / 1 </span>
<span>If you notice, since the denominator is 1, this is simply: </span>
<span>x = 2.89 / 4.25 </span>
<span>So the unit cost is just $2.89 divided by the number of ounces (4.25). </span>
<span>Plug that into your calculator and you get: </span>
<span>0.68 </span>
<span>That's in dollars. So if you want it in cents, move the decimal point 2 places to the right. </span>
<span>Answer: </span>
<span>$0.68 per ounce </span>
<span>or </span>
<span>68 cents per ounce</span>
