you can do the same for the remining sums

so a is 1/2 in which 2 is raised to 6 so answer is 1/64

Shawna took a test that had a total of 20 items. She got 4/5 of the items correct. How many items did she get correct?

ehidna [41]

Shawna got 16 items correct

Step-by-step explanation:

To find the percentage of answers or part of total answers we multiply the fraction with the total number of items.

Given

Total items on test = 20

Correct items fraction = 4/5

Then,

$Correct\ items=\total\ items * \fraction\ of\ correct\ answers\\= 20 * \frac{4}{5}\\=\frac{80}{5}\\=16$

Shawna got 16 items correct
