Answer: Incorrect.

Step-by-step explanation: 24 out of 30 is 80.00%.

Step 1: We make the assumption that 30 is 100 % since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100 % = 30.

Step 4: In the same vein, x % = 24 .

Step 5: This gives us a pair of simple equations:

100 % = 30(1).

x % = 24(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100 % / x % = 30/24

Step 7: Taking the inverse (or reciprocal) of both sides yields

x/100 = 24/30

x = 80 %

Ivan

Answer:

18

Step-by-step explanation:

If the average of 6 numbers is 10, then the sum of those 6 numbers is:

6 x 10 = 60

To calculate the sum of the remaining 10 numbers, subtract 60 from the total sum of all the numbers:

240 - 60 = 180

Therefore, the average of the 10 remaining numbers:

180 ÷ 10 = 18
