If you have the two numbers 5 and 7, You would make it 5/7. That means you just took two WHOLE numbers and put them together into a FRACTION. Thatmeans the number is not whole yet. In this case you would need 2/7 more peices to make a whole, witch would be one.
To convert 0.7 into a fraction, place the 7 over 10 (0.7 is 7 tenths). It is 7/10.
7/8, x100 is 87.5%
5 and 2/7 as an improper fraction is 37/7
To convert a proper fraction to an improper fraction you multiply the whole number by the denominator plus the nominator and put your answer in your nominator spot over your same denominator. EXAMPLE:7 and a half converted into a improper fraction would be 15 over 2.
The way to figure this out is to convert the whole number into a fraction with the same denominator as the fraction being subtracted. Let's do this one. 1 - (5/12) = (12/12) - (5/12) = At this point, you have 12 over 12 minus 5 over 12, and to work a fraction like that where you have a common denominator, you can take the numerators and subtract them and put the result over 12. It will look like this: (12 - 5) / 12 = 7/12 That 7/12 is your answer. You don't even have to reduce it.
To convert 0.7 into a fraction, place the 7 over 10 (0.7 is 7 tenths). It is 7/10.
7 over 10 or 7/10
5 over 7
2 5/7 as an improper fraction is 19/7 nineteen over seven
7/8, x100 is 87.5%
The answer is whatever you would like to have it converted to. Do you want another equivalent fraction ? A mixed number ? A decimal ? The answer is different in each of these cases.
For subtraction, you need to first convert to common denominator. Multiply top and bottom of first fraction by 7. Multiply top and bottom of second fraction by 5 8 and 2/5 = 42/5 = 294/35 4 and 5/7 = 33/7 = 165/35 Now subtract the numerators, and put the result over the common denominator. 294 - 165 = 129/35 Next check to see if the fraction can be simplified. 35 = 7 X 5 129 doesn't end in 5 or 0, so it is not evenly divisible by 5. Next check to see if 7 goes evenly into 129. No, it doesn't, so the fraction is in simplest form. You could convert it into a mixed number or leave it as an improper fraction. Answer: 129/35
Multiply the whole number and the bottom # of the fraction, add the total with the top # of the fraction, then put over the bottom # of the fraction (ex 2 3/4 -> 4x2+3 -> 11/4)
5 and 2/7 as an improper fraction is 37/7
35 as a fraction of 5 is 7/1 or simply 7.
5 over 8 as a fraction plus 7 over 12 = 15/24
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. Therefore, the fraction 5/7 divided by 7/9 is equal to (5/7) × (9/7) which simplifies to 45/49.
