35 is what percent of 150? Enter your answer in decimal form to the nearest hundreth.
Sophie [7]

Answer:

23.33%

Step-by-step explanation:

Solution for 35 is what percent of 150:

35: 150*100 =

(35*100): 150 =

3500: 150 = 23.33

Now we have: 35 is what percent of 150 = 23.33

Question: 35 is what percent of 150?

Percentage solution with steps:

Step 1: We make the assumption that 150 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%=150.

Step 4: In the same vein, x%=35.

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

100%=150(1).

x%=35(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

\frac{100\%}{x\%}=\frac{150}{35}

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

\frac{x\%}{100\%}=\frac{35}{150}

Therefore, 35 is 23.33% of 150.

Please help me answer this step by step would be helpful
UNO [17]

Answer:

Step-by-step explanation:

The viniculum in a fraction represents subtraction with exponents.

Subtracting exponents gives us  3^12/3^8 * 3^2

Simplifying gives 3^12/3^10. Then, we can achieve 3^12 - 3^10.

This equals 3^2.

3^2 = 9.

So 9 is the answer of your question.
