Letty answered 15 out of 20 questions correctly on her history quiz. What
Furkat [3]

Answer:

75%

Step-by-step explanation:

One way to find this out is to divide 15 by 20

15/20 can be simplified into 0.75.

Another example:

Let's say a student does absolutely horrendus on the test, and gets only 4 questions correct out of 20. You can do 4/20 which is 0.2 in decimal form. (You can use a calculator.) This means that in this example, this student got a 20% on the test.
