Help me please i dont know.
i got wrong but i don't think they are all wrong though

a= .3 , b= .4 , c= 40% and d=15%

Step-by-step explanation:

each one of the marks represents either 10% or .1 so since a is stretched over 3 of the marks it would be .3

same thing applies for b, c and d

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

part d

step-by-step explanation:
