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!
Answer:
3n + 5 =60
Step-by-step explanation:
Answer : n=55/3
Let's put this in terms of a system of equations. Let's call the numbers x and y, with x being the larger integer and y the smaller one. Since they are consecutive odd integers, we know that:
x = y + 2
The constraint is:
xy= 3(x+y) + 71 Simplify
xy = 3x + 3y + 71 Plug in (y+2) for x:
(y + 2) y = 3(y + 2) + 3y + 71 Simplify
y² + 2y = 3y + 6 + 3y + 71 Subtract 6y from both sides, add 71+6
y² -4y = 77
y² - 4y - 77 = 0
Factor:
(y - 11) (y+7) = 0
y = 11 or y=-7
When y = 11, x = 13, since x = y+2
Plug in to make sure:
xy = 3(x+y) + 71
11*13 = 3 (11 + 13) + 71
143 = 3 (24) + 71
143 = 72 + 71
143 = 143
Our values work!
