Hey there!
So, when finding who completed more, we would want to find the lowest denominator, but also, we would have to compare it with the numerator.
John: He completed 2/3, which is basically almost done.
Sarah: She only completed (half) of her homework.
Alex: He only did 7/8
Michelle: He/she only did 1/2, which is only half.
So, from looking at these fractions above, Michelle and Sarah are out.
We would just have to determine, which is finished more, John or Alex.
John had 2/3 & Alex 7/8
So, by comparing them both, 7/8 would be greater because the smaller the denominator is, and the closer that the numerator is to the denominator, this would mean that the homework is almost finished.
Your correct answer is Alex, he has completed more.
Hope this helps you!
The perimeter is defined as the sum of all the sides of any polygon.
A rectangle is a polygon with 4 sides and 2 pairs of parallel sides. Therefore, in order to find the perimeter of any rectangle, we can either add up all the sides given to you or use a formula which states that:
P = 2L + 2W
Where,
L is the length of the rectangle and W is the width of a triangle.
For example:
A triangle with length = 5 cm and Width = 3 cm.
The Perimeter will be:
P = 2×5 + 2×3
P = 10 + 6
P = 16 cm
Answer:
B = <u>d - 3f²</u>
5M
Step-by-step explanation:
d -3f² = 5 B B
5 BM = d - 3f²
B = <u>d - 3f²</u>
5M
Add 1 to both sides:
In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that
Under this assumption, we square both sides and we have
The solutions to this equation are
But since we can only accept solutions greater than -1, we discard 
and accept 
.
In fact, we have
and
which is the only solution.
