To get the answers to these questions, you will need to apply some mathematical concepts related to ratios, percentages, fractions, and decimals. I will guide you through the process of finding the answers step by step.
1. Write a ratio and a percent for the shaded area.
To find the ratio, you need to write the number of shaded blocks over the total number of blocks in the grid. In this case, it is 6 shaded blocks out of 20 total blocks (4 x 5 grid). So the ratio is 6/20. To find the percent, you can convert the ratio to a decimal by dividing 6 by 20 and then multiply by 100. So the percent is (6/20) x 100 = 30%.
2. Write the ratio as a percent.
To convert a ratio to a percent, you need to multiply the ratio by 100. In this case, the ratio is 19/25. So the percent is (19/25) x 100 = 76%.
3. Write the decimal as a percent.
To convert a decimal to a percent, you multiply the decimal by 100. In this case, the decimal is 0.09. So the percent is 0.09 x 100 = 9%.
4. Write the percent as a decimal.
To convert a percent to a decimal, you divide the percent by 100. In this case, the percent is 37.1%. So the decimal is 37.1 / 100 = 0.371.
5. Order from least to greatest.
To order these numbers, you need to compare them. The smallest number is 0.8. Then, you compare seven-eighths with other numbers. In decimal form, seven-eighths is 0.875. So the order from least to greatest is 0.8, seven-eighths, 81%, nineteen-twenty-fifths.
6. What percent of the calories are from sugar?
To find the percent of calories from sugar, divide the calories from sugar (165) by the total calories in the candy bar (250) and multiply by 100. So the percent is (165/250) x 100 = 66%.
7. Write the fraction as a percent.
To convert a fraction to a percent, divide the numerator by the denominator, then multiply by 100. In this case, the fraction is 4/15. So the percent is (4/15) x 100 = 26.7%.
8. Write the fraction as a percent.
To convert a fraction to a percent, you divide the numerator by the denominator and multiply by 100. In this case, the fraction is 52/5. So the percent is (52/5) x 100 = 1040%.
9. Write the percent as a decimal and a fraction.
To convert a percent to a decimal, divide the percent by 100. In this case, the percent is 365%. So the decimal is 365 / 100 = 3.65. To write the fraction, divide the percent by 100 and simplify if possible. In this case, 365% simplifies to 313/20.
10. Percentage of decrease in the number of T-shirts sold.
To find the percentage of decrease, subtract the initial number of T-shirts sold (25) from the final number (18), divide the result by the initial number, and multiply by 100. So the percent of decrease is ((25 - 18) / 25) x 100 = 28%.
11. Percent of toy robots that are defective.
To find the percent of defective toy robots, divide the number of defective robots (40) by the total number of robots (150) and multiply by 100. So the percent is (40/150) x 100 = 26.67%.
12. How much did you earn this year?
To find out how much you earned, divide the amount you need to invest in the stock market ($435) by the percentage required to invest (15%) and divide the result by 100. So the amount you earned is (435 / 15) x 100 = $2,900.
13. 30% of what number is 60?
To find the number, divide the given value (60) by the decimal equivalent of the percentage (30/100) and divide the result by 100. So the number is (60 / (30/100)) / 100 = 200.
14. Estimate a 20% tip for a meal that cost $42.50.
To estimate the tip, multiply the cost of the meal ($42.50) by the decimal equivalent of the percentage (20/100). So the estimated tip is 42.50 x (20/100) = $8.50.
15. Total amount paid for the limousine rental, tax, and tip.
To calculate the total amount paid, add the bill for the evening ($70.00) to the tax (8% of the bill) and the tip (20% of the bill before tax is added). So the total amount paid is $70.00 + (0.08 x $70.00) + (0.20 x $70.00) = $89.60.
16. Percent of markup.
To find the percent of markup, subtract the original price ($33.00) from the new price ($45.00), divide the result by the original price, and multiply by 100. So the percent of markup is ((45.00 - 33.00) / 33.00) x 100 = 36.4%.
