Are you asking what are like fractions? If so, like, or alike fractions are two fractions with the same denominator, (the bottom number of the fraction).
For example, 1/10 and 7/10. If that was not what you were asking, please let me know and I'll try my best. Hope this helped you!
Answer:
$2.50
Step-by-step explanation:
Let's set up a proportion using the following setup.
price / pens = price / pens
We know that it costs $4.00 for 8 pens.
$4.00 / 8 pens = price / pens
We don't know how much it costs for 5 pens. Therefore, we can say it costs $x for 5 pens.
$4.00 / 8 pens = $x / 5 pens
4/8=x/5
We want to solve for x (the cost for 5 pens). Therefore, we must get x by itself on one side of the equation. x is being divided by 5. The inverse of division is multiplication, so multiply both sides of the equation by 5.
5*(4/8)=(x/5)*5
5*(4/8)=x
5*0.5=x
2.5=x
x= $2.50
Ivan should pay $2.50 for 5 pens.
Answer:
Take two point from the table, doesn't matter which ones, because this is linear. I will choose (0,0) and (3,.5).
Now follow the equation for slope: m = change in y / change in x.
The slope is 1/6. m=1/6
Its y-intercept is at 0. b=0
So the equation is y = 1/6x. The graph is attached.
-12.6 as a percent is -1260%
