30% = 30/100
= 0.3
Now if we say that x% of a number is y then it actually means that x% multiplied by that number would be equal to y, thus:
30%*56 = 0.3*56
= 16.8
Answer:
D
Step-by-step explanation:
Answer:
13, 14, 15, 16
Step-by-step explanation:
Call the first number n. Then the next three consecutive numbers (assuming integers) are n + 1, n + 2, n + 3.
The mean is the total of the numbers divided by how many there are.
Simplify and multiply by 4.
The first number is 13.
The median is 14.5, halfway between the "middle" numbers 14 and 15. This is just a check; no additional equation is necessary.
Answer:
65%
Step-by-step explanation:
Make it a fraction:
Divide 13 by 20:
13÷20
Write it as a decimal:
0.65
Move the decimal 2 places to the right:
6.5
65.
Put the percent sign at the end:
65%
