Bradley answered 80% of the questions on his science test correctly. There were 30 questions on the test, and all the questions had equal value. How many questions did Bradley answer correctly on his test?
Answers
Answer:
24 correct questions
Step-by-step explanation:
The resulting number is how many questions he got right.
Subtract that number from the total of 30, and you'll know how many he got wrong.
You can also do it as a fraction - 80% out of 100% is 80/100, or 4/5. So he got 4/5 right and 1/5 wrong.
30 multiplied by 1/5 is the same as 30 divided by 5. So 30 divided by 5 will be how many questions he got wrong.

using rules of exponents, 7^6/7^2 is 7^4 (just subtract 2 from 6)
D is the only one that equals 7^4, as 2 times 2 is 4.
