Danny took a math test and got 35 correct and 10 incorrect answers. What was the percentage of the correct answers? (Round your answer the the nearest hundredth) A student earned a grade of 80% on a math test that had20 problems. How many problems on this test did the student answer correctly? (round to the nearest whole number)

1. 78%

2. 16

Step-by-step explanation:

35 + 10 = 45

Danny got 35/45 answers correct.

Divide 35 into 45

35 ÷ 45 = .777777778

.777777778 ≈ .78

To convert a decimal to a percentage, move the decimal point two spaces behind.

.78 = 78%

Danny got 78% of the answers correct.

80% = .8 =

Multiply by 20 to get the answer

× =

Simplify

= 16

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5
