Answer:
4 1/2
Step-by-step explanation:
Apply the fractions formula for division, to
3/4÷1/6
and solve
3/6x4/1
=18/4
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(18,4) = 2
18/24÷2/2=9/2
Convert to a mixed number using
long division for 9 ÷ 2 = 4R1, so
9/2=4 1/2
Therefore:
3/4÷1/6=4 1/2
The piece Zoe cut off would be 1 and 5/12 ft long.
5 and 1/4 - 3 and 5/6
The least common denominator is 24.
5 and 6/24 - 3 and 20/24
5 and 6/24 becomes 4 and 30/24
4 and 30/24 - 3 and 20/24 = 1 and 10/24
1 and 10/24 can be simplified to 1 and 5/12.
Okay, so -
We have one very important thing here. This little part <em>6 - (-3). </em>
Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive!
So, our question is essentially <em>5 + 6 + 3 - 8 + 4 - 3 = ?</em> instead of <em>5 + 6 - (-3) - 8 + 4 - 3!</em> =)
With that in mind, we simply solve left to right.
<em>11 + 3 - 8 + 4 - 3 = ?</em>
<em>14 - 8 + 4 - 3 = ?</em>
<em>6 + 4 - 3 = ?</em>
<em>10 - 3 = ?</em>
<em>7</em> is our final answer! =)
D is the correct answer<span />
