can you check these?
i need to write each fraction or decimal as a percent round to nearest tenth of a percentif necessary?
21) 7/5 = 140%
22) 137/100 = 137%
23) 0.8/100 = .8%
24) 21/4 = 525%
25) 17/10 = 170%
26) 65/40= 163%
27) 37/20 = 185%
28) 7/500 = 1.4%
29) 9/8 = 13%
Just question 23 will be 8% the rest i see them okay
I disagree. 23 is correct, but 26 is 162.5% and 29 is 112.5% if rounding to nearest tenth of a percent. (9 is greater than 8, so answer must be greater that 100%.)
Let's go through each fraction or decimal and convert it to a percent, rounding to the nearest tenth of a percent if necessary:
21) 7/5 = 7 divided by 5. To convert it to a percent, we multiply by 100. So, (7/5) x 100 = 140%.
22) 137/100 = 137 divided by 100. To convert it to a percent, we multiply by 100. So, (137/100) x 100 = 137%.
23) 0.8/100 = 0.8 divided by 100. To convert it to a percent, we multiply by 100. So, (0.8/100) x 100 = 0.8%.
24) 21/4 = 21 divided by 4. To convert it to a percent, we multiply by 100. So, (21/4) x 100 = 525%.
25) 17/10 = 17 divided by 10. To convert it to a percent, we multiply by 100. So, (17/10) x 100 = 170%.
26) 65/40 = 65 divided by 40. To convert it to a percent, we multiply by 100. So, (65/40) x 100 = 163%.
27) 37/20 = 37 divided by 20. To convert it to a percent, we multiply by 100. So, (37/20) x 100 = 185%.
28) 7/500 = 7 divided by 500. To convert it to a percent, we multiply by 100. So, (7/500) x 100 = 1.4%.
29) 9/8 = 9 divided by 8. To convert it to a percent, we multiply by 100. So, (9/8) x 100 = 112.5%. Rounding it to the nearest tenth of a percent gives us 113%.
So, the correct conversions are:
21) 7/5 = 140%
22) 137/100 = 137%
23) 0.8/100 = 0.8%
24) 21/4 = 525%
25) 17/10 = 170%
26) 65/40 = 163%
27) 37/20 = 185%
28) 7/500 = 1.4%
29) 9/8 = 113%
To write each fraction or decimal as a percent and round to the nearest tenth of a percent if necessary, you can follow these steps:
21) 7/5:
To convert a fraction to a decimal, divide the numerator by the denominator.
7 ÷ 5 = 1.4
To convert a decimal to a percent, multiply by 100.
1.4 × 100 = 140%
So, 7/5 is equal to 140%.
22) 137/100:
Divide the numerator by the denominator.
137 ÷ 100 = 1.37
Multiply by 100 to convert to a percent.
1.37 × 100 = 137%
So, 137/100 is equal to 137%.
23) 0.8/100:
Divide the numerator by the denominator.
0.8 ÷ 100 = 0.008
Multiply by 100 to convert to a percent.
0.008 × 100 = 0.8%
So, 0.8/100 is equal to 0.8%.
24) 21/4:
Divide the numerator by the denominator.
21 ÷ 4 = 5.25
Multiply by 100 to convert to a percent.
5.25 × 100 = 525%
So, 21/4 is equal to 525%.
25) 17/10:
Divide the numerator by the denominator.
17 ÷ 10 = 1.7
Multiply by 100 to convert to a percent.
1.7 × 100 = 170%
So, 17/10 is equal to 170%.
26) 65/40:
Divide the numerator by the denominator.
65 ÷ 40 = 1.625
Multiply by 100 to convert to a percent.
1.625 × 100 = 162.5%
Rounding to the nearest tenth of a percent, it becomes 163%.
So, 65/40 is equal to 163%.
27) 37/20:
Divide the numerator by the denominator.
37 ÷ 20 = 1.85
Multiply by 100 to convert to a percent.
1.85 × 100 = 185%
So, 37/20 is equal to 185%.
28) 7/500:
Divide the numerator by the denominator.
7 ÷ 500 = 0.014
Multiply by 100 to convert to a percent.
0.014 × 100 = 1.4%
So, 7/500 is equal to 1.4%.
29) 9/8:
Divide the numerator by the denominator.
9 ÷ 8 = 1.125
Multiply by 100 to convert to a percent.
1.125 × 100 = 112.5%
Rounding to the nearest tenth of a percent, it becomes 113%.
So, 9/8 is equal to 113%.
