My answers
1.A
2. ???
3. B
4. ???
Thanks if anyone can help me ahead of time.
#1, ok
#2
.245 = 24.5% , move decimal 2 places to right, tag on the % sign
#3
28% = .28 = 28/100 = 7/25, so C
#4
.367 -----> .367
36.5% --- > .365
9/25 -----> .36
so what do you think?
1.A - yes
2. ??? Multiply by 100 or move the decimal point two places to the left.
3. B - No
4. ??? - Change them all to decimals.
oh okay I understand this more now. Thanks so much for helping me with these problems. So number two is C?
Didn't you see Reiny's answer?
He's right. I was wrong.
Rainy gave me a 40 %
I have 5 questions...
Let's go through each question and explain how to find the correct answer:
1. Rename 7/20 as a percent:
To convert a fraction to a percent, you can divide the numerator (7) by the denominator (20) and multiply by 100.
Calculation: (7 ÷ 20) × 100 = 35
Therefore, the fractional value 7/20 is equal to 35%.
Answer: A. 35%
2. Rename 0.245 as a percent:
To convert a decimal to a percent, you can simply multiply by 100.
Calculation: 0.245 × 100 = 24.5
Therefore, the decimal value 0.245 is equal to 24.5%.
Answer: B. 24.5%
3. Rename 28% as a decimal and fraction in its simplest form:
To convert a percent to a decimal, you divide it by 100.
To convert a percent to a fraction, you put it over 100 and simplify (if possible).
Calculation: 28 ÷ 100 = 0.28
For the fraction, we can simplify 28/100 by dividing the numerator and denominator by their greatest common factor, which is 4.
28 ÷ 4 = 7
100 ÷ 4 = 25
Therefore, the decimal value of 28% is 0.28, and the simplest form of the fraction is 7/25.
Answer: A. 0.28 and 28/100
4. Put 0.367, 36.5%, and 9/25 in order from least to greatest:
To compare numbers, we can convert them to a common format. In this case, we can convert the percent to a decimal and the fraction to a decimal by dividing the numerator by the denominator.
0.367
36.5% = 36.5 ÷ 100 = 0.365
9/25 = 9 ÷ 25 = 0.36
Now we can arrange these decimals from least to greatest:
0.367 < 0.36 < 0.365
Therefore, the correct order is:
0.367, 9/25, 36.5%
Answer: 0.367, 9/25, 36.5%
I hope this helps! Let me know if you have any further questions.
