First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.

How do you change 0.8 into a fraction?
since the last number (8) is in the tens place you have 10 as the denominator (same for thousandths = 1000 as denominator, hundredths = 100 as denominator and so on) then put the decimal number as the numerator and you get the answer of 8/10
How do you change a percent into a fraction?
One way to change a percent into a fraction is to take the percent number and but the denominator as 100. For example if the percent number was 43 then that would be your numerator and 100 would be your denominator so it should be 43/100. Percent means out of 100 so your denominator should be 100 unless you simplify your fraction.
How do you change a proper fraction into a inproper?
Multiply it by a number that is large enough so that the numerator of the fraction becomes larger than its denominator.
How do you change 3 into a fraction?
u borrow from the three change the 3 to a 2. them u put a fraction next to the whole number ...... whatever the other fraction's denominator is you have to put for the fraction for the numerator and the denominator so for example the other fraction has 2 over 6 so for the fraction where ur borrowing you have to put 6 over 6 since u borrowed a whole from 3 I knw its confusing but ull get it eventually ur welcome too :)
How do you write 2 and 3 over 8 as improper fraction?
The numerator of the improper fraction will be 2*8 + 3 = 19 and the denominator will remain the same as that for the fractional part of the mixed fraction. So the improper fraction is 19/8.
What the fraction of 0.7 but same denominator as 4?
4 is an integer and so has denominator 1. 0.7 is a proper fraction and cannot have a denominator of 1.
How does the value of a fraction change if you double the denominator?
If you double the denominator of any fraction, the number of unit fractions stays the same but each unit fraction is half as big. So the value of the fraction is half what it was when you double the denominator. 2×(5/8)=(2×5)/8=10/8
What part of the fraction does not change when you add or subtract?
If you find the common denominator for the fractions, then the bottom will stay the same :) BUT sometimes it is diffacult to find the common denominator so you may need help

What is the rule for subtracting fractions?
First, change it so that the two fractions have the same denominator (by changing the fractions into equivalent fractions). Once the two fractions have the same denominator, it is simply a case of subtracting the numerators, leaving the denominator the same. Finally, reduce the fraction to its lowest terms (if possible).
How do you answer fraction problems?
The best way to answer fraction problems is with a fraction that has the same denominator or a common denominator with those in the original problem. Typically you also need to reduce it so that the final answer does not contain an improper fraction.

How do you change an mixed fraction to an improper fraction?
ex.1 2/3 take the base number and multiple that by the denominator and add by the numerator andAwhatever you get for that is your new numerator but you denominator stays the same as the last one so for this example you should get 5/3.
How do you simplify a fraction when the numerator and denominator is the same number?
If the numerator and denominator are the same then their GCF is also the same number. So the fraction can be written, it is simplest form as the integer, 1.
How do you simplify a fraction numerator and denominator the same number?
If the numerator and denominator are the same then their GCF is also the same number. So the fraction can be written, it is simplest form as the integer, 1.
When converting a decimal to a fraction what determines the denominator of the fraction?
The denominator of the fraction is determined by the number of decimal places in the decimal number. If there is one decimal place, the denominator will be 10. If there are two decimal places, the denominator will be 100, and so on.
What is the reciprocal for seven over three?
The reciprocal of a fraction is basically the same fraction flip-flopped. So the numerator becomes the denominator, and the denominator becomes the denominator. So for seven over three, the reciprocal would be three over seven.
