To subtract 2 fraction we have to make common denominator.

- its the simpest form
We need to find the percent, let's start but making the equation.
The price is 2.69
The tax cost is 0.13
So what percent of 2.69 is = 0.13.
Equation: X/100 x 2.69 = 0.13
Multiply each side by 100 so we can get x alone with the price: 2.69x = 13
Now to get x alone, we must divide both sides by 2.69: x = 4.8
Finally, we just round 4.8 to the nearest whole number, which is 5 (5 or above give it a shove, 4 or below let it go, we have 8 so we give it a shove). This means that the answer will be 5%.
I hope this helps! :)
So what I have gotten from this is the dates 1 Jan -8 Jan they where gone 7 days so look at the prices of the per night I hope it helps
If both are similar ratio of sides will be same

Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.
Your equation should look like:
5h + 20 = 90
Subtract 20 from both sides.
5h = 70
Divide both sides by 5.
h = 14
Gina can rent a surfboard for 14 hours if she has $90.
