Colin got 16 out of 80 correct in his test. What fraction of the marks did he get correct? Give your answer in its simplest form.

Step-by-step explanation:

Lets divide 16 (# correct) by 80 (total # of questions)

16/80

(1*16)/(5*16)

1/5

Colin got one fifth of the test correct

Thus, the answer is 1/5

hello from mrbilldoesmath!

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
