You multiply 40% by 90. Or make 40% 0.4 and multiply that by 90.
Answer:
36
Step-by-step explination
You should take 40% then put it into decimal form. You should get 0.4 then multiply that by 90 and you should get 36.

Answer:
The amount of fabric needed for 8 pillows is of a yard.
Step-by-step explanation:
We are given that,
Amount of fabric Amy uses for each pillow = of a yard.
It is required to find the amount of fabric needed for 8 pillows.
So, we have,
The amount of fabric for 1 pillow =
The amount of fabric for 8 pillows = =
Hence, the amount of fabric needed for 8 pillows isof a yard.
Amy will need 5 1/3 yards of fabric in order to make 8 pillows. This represents the total amount of fabric required for all 8 pillows, considering she uses 2/3 of a yard for each pillow.
To find the total amount of fabric Amy will need to make 8 pillows, we can use the concept of multiplication. Since she uses 2/3 of a yard of fabric for each pillow, we can multiply the amount of fabric required for one pillow (2/3 yard) by the number of pillows (8) to get the total amount.
Total fabric needed = (2/3) * 8
Now, perform the calculation:
Total fabric needed = 16/3 yards
To write the answer in simplest form, we can simplify the fraction:
Total fabric needed = 5 1/3 yards
Therefore, Amy will need 5 1/3 yards of fabric in order to make 8 pillows. This represents the total amount of fabric required for all 8 pillows, considering she uses 2/3 of a yard for each pillow.

Final answer:
Unit conversion and dimensional analysis, based on equivalent ratios, can solve real-world problems. They help in practical scenarios, like converting cooking measurements or understanding distances in different countries. The metric system, based on powers of 10, is particularly convenient for such conversions.
Explanation:
Conversion of measurements, also known as unit conversion and dimensional analysis, can help solve real-world problems in various practical scenarios. For example, a person reading a European cookbook in the United States might require conversion of quantities expressed in liters into cups. Likewise, a Canadian tourist driving through the U.S. might need to convert miles on road signs into kilometers to gauge distances accurately.
It's crucial to understand that a ratio of two equivalent quantities expressed with different measurement units can be used as a unit conversion factor. Suppose, the lengths of 2.54 cm and 1 in are equivalent, so you can derive a conversion factor from this ratio. Various other commonly used conversion factors can make this process easier in daily life, such as converting a basketball player's vertical jump from inches to centimeters or converting cooking measurements.
The metric system is particularly convenient for unit conversion as it is based on powers of 10, so conversions between metric units can be done by simply moving the decimal place. However, dimensional analysis and unit conversion are universally applicable tools that can make life easier, from understanding distances to making recipes to making scientific calculations.

Hey there! Let me help you!
To find what the reciprocal is, you have to turn a proper fraction upside down. For example, the reciprocal of 2/8 would be 8/2. However, when you have an improper fraction, you must first turn it into an improper fraction. To turn a mixed number into an improper fraction, multiply the denominator by the whole number and add the numerator. The denominator will stay the same. For example, to turn 2 3/8 into an improper fraction, multiply 8 by 2 and add 3. That equals to 19. The denominator will stay the same. So, the improper fraction for 2 3/8 is 19/8. Now, turn 19/8 into a reciprocal. 19/8 as a reciprocal would be 8/19.
Thank you!
The reciprocal of fraction 2(3/8) is 8/19.
We have,
To find the reciprocal of a number, we invert the fraction by swapping the numerator and denominator.
Given the number 2 3/8, we first convert it to an improperfraction:
2 3/8 = (2 * 8 + 3) / 8 = 19/8
To find the reciprocal, we invert the fraction by swapping the numerator and denominator:
Reciprocal = 8/19
Therefore,
The reciprocal of fraction 2(3/8) is 8/19.
