Answer:
[tex] \frac{x}{40} = \frac{75}{100} [/tex]
So he missed 10 questions and got 30 right
Step-by-step explanation:
To find the answer we need to find how many times 40 can go into 100. it can go into 100 exactly 2.5 times. So 2.5 times 40 will equal 100(100%) This also means that 2.5 times X should also equal 100.
To find X we can do 75 divided by 2.5. When we do this, we get 30. So he got 30 questions right and missed ten.
Another way to find the answer is to just do 0.75 or 75% times 40(total amount of questions)
