What is 80% as a simplified fraction

4/5

Step-by-step explanation: To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. In this case, 80% can be written as the ratio 80 to 100 of 80/100. Notice however that 80/100 is not in lowest terms so we need to divide both the numerator and denominator by the greatest common factor of 80 and 100 which is 20.

80 ÷ 20 = 4

100 ÷ 20 = 5

Therefore, 80% can be written as the fraction 4/5 which is in lowest terms.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
