if it were 5 and 1/2 you would multiply 5 by the denominator: 5x2 and add the numerator: 10+1. Then you would put that number over 2. so 11/2
I suggest you convert the fractions to a common denominator; that should make it easy to compare them.
Say you have 5 and 1/10 and you have to add 6 and 3/20, you add the whole numbers, (11) and then convert the 10 of 1/10 to 20 (20/10 is 2), then you have to multiply the 1 by 2 to get 2/20 (equivalent fraction of 1/10). Now you can add the fractions, i.e. 4/20 (or simplified, 1/5). Final answer is 11 and 1/5
0.3 = 3/10 in fraction
Fractions that multiply to get 1 whole are reciprocals, or multiplicative inverses.
0.833 cups is equivalent to 5/6 cups. To convert decimal fractions to common fractions, you can multiply the decimal by a power of 10 to make it a whole number. In this case, 0.833 multiplied by 100 gives 83.3, which simplifies to 5/6 when divided by 10.
The numbers from least to greatest are: 2 over 10, 1/2, 0.6 and 0.9 (which is equal to 9 over 10). Convert all the fractions to decimals to compare.
0.5 = 5/10 or 1/2 in fraction
equivalent fractions for 10 over 4 = 5/2, 20/8, 30/12
No Because a fraction is written in two parts a whole is just 1 or 10 or just a number which is equal has no left over fractions or decimals . Hope this helped!!
To compare, convert both fractions to a common denominator: 3/5 = 6/10 1/2 = 5/10 6/10 > 5/10, so 3/5 > 1/2.
12/3 - 21/2 = 1x3+2/3 - 2x2+1/2 (convert to improper fractions) = 5/3 - 5/2 = 5x2/3x2 - 5x3/2x3 (convert to equivalent fractions with same denominator) = 10/6 - 15/6 = 10-15/6 = -5/6
