On 88 question to leebeth missed 11 question was has that gread for that test

assuming the test is worth 100 points.

there were 88 questions in total, she missed 11, meaning she answered 88 - 11 = 77, assuming her grade is those 77 correct ones.

if 88 is the 100%, what is 77 off of it in percentage?

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
