Okay. Let us do it surgically. Let us solve first the rate of increase in Lliana's Math grade. 86-65 = 21, thus the rate can be written as a fraction 21/65. We will reserve the decimal form once we are done with both rates of increase.
On the same note, Fiona's increase in Math grade is determined by subtracting 70 from her recent grade of 80, thus giving us an increase in her grade by 10. Therefore, the rate of increase in her Math grade is 10/70.
Now, let us take the decimal forms of the students' grade in math respectively. Lliana's is 21/65 or 0.32307692307... Fiona's is 10/70 or 0.14285714285. Now, subtracting this decimals we have 0.18021978021.
Changing it to percent form, we must multiply it by 100 and add the symbol "%". Therefore, we have 18.021978021 %.
Finally, rounding the value to the nearest whole number, we obtained 18.00% or just 18%.

Answer:
Angles in the same segment of a circle are equal
Step-by-step explanation:
if a line join two points subtends equal angles at two other points on the same side of that line segment,then the four points are concyclic
Yes you just have to cross multiply
When you have
you can solve the equation by multiplying both sides by 1/4. Then simplify.
