Why is it useful to write a ratio of a fraction as a unit rate?
For people who are not familiar with fractions it is easier to compare them in the form of unit rates.
What are fractions with the numerator 1 called?
A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n.
How are all unit fractions alike and different?
Unit fractions all have the same numerators but the denominators can be different.
If you move the decimal point to the right we are moving from a?
One unit to a unit which is a multiple of ten times as small.
How do you write 8.517 in unit form?
It can be rounded to 9 units.
Is it true that ancient Egyptians thought that all fractions could be written as unit fractions?
No. They thought that all fractions could be expressed as combinations of unit fractions. They and other ancients may have thought that any fraction could be wretten as a combination of unit fractions, but according to wikipedia they (ancient Egyptians) had special symbols for 2/3 and 3/4 and even had a papyrus used by scribes that listed the equivalents for 2/n, so they did not always write fractions as this combination of unit fractions. Does your question mean a combination of unit fractions, or as a unit fraction?

How can you write ratios of fractions as unit rates in order to solve problems?
To write ratios of fractions as unit rates, first express the ratio as a single fraction by dividing the two fractions. This can be done by multiplying the first fraction by the reciprocal of the second. Once converted into a single fraction, simplify it to find the unit rate, which shows how much of one quantity corresponds to one unit of another. This method helps to solve problems by providing a clear comparison between the two quantities involved.
Can any fraction be expressed as the sum of two unit fraction?
Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.Yes, but only if negative unit fractions are included.For example 3/7 = 1/2 - 1/14but I do not think there are positive unit fractions that will do.
What is four fourths?
It is a whole unit, so the answer is one.
How do you do unit fractions?
How would we do it well remember a unit fraction always has one as a numerator. So 2/3 would be 1/3 plus 1/3. These are the unit fractions. It's got a 1 is a numerator all right 5/6 would be a 1 6.
What is a unit in fractions?
A unit = 1 = 1/1 in fraction form.
How do you write sq ft in fractions?
Numbers, including fractions, don't have units. It doesn't matter whether the number is positive, negative, exponential, rational, transcendental, mixed, imaginary, natural, or a fraction. The unit is always written after the number.
What are Unit fractions?
Unit fractions are fractions where the numerator is 1 and the denominator is a positive integer. They represent a single part of a whole that is divided into equal parts. For example, 1/2, 1/3, and 1/4 are all unit fractions. These fractions are often used in mathematical concepts, including the study of rational numbers and in partitioning whole numbers.
What are the unit fractions for 78?
78/1
How long is three fourths in feet?
To convert three fourths to feet, we need to know what we are converting. If we are converting three fourths of a foot to feet, then it would be 0.75 feet. However, if we are converting three fourths of a different unit (such as inches or yards) to feet, we would need to know the conversion factor for that unit to feet.
How many one-fourths go into 20?
Division of fractions. 20 divide 1/4 = 20/1 divide 1/4 Remember the rule for division of fractions CHANGE THE SIGN TO MULTIPLY AND INVERT THE DENOMINTING (RHS) FRACTION. Then proceed as multiplying fractions. Hence 20.1 X 4/1 = 80/1 = 80 ( NB The '1' is trivial). NB If you cannot 'get a handle' on this answer, think ; in one unit there are four quarters. so in two units there are eight quarters, so it follows that in 20 units there are 80 quarters.
