First get the fraction to a common denominator:
7 3/10 - 3 1/2 = 7 3/10 - 3 5/10 = (73 - 35)/10 = 38/10 =
or 3 4/5 or 3.8
When the fraction is on a common denominator, multiply in the integer part, to get the complete number in the fraction - here 10.
Then, to get the result, divide the denominator into the numerator to get the nearest whole number plus the remaining fraction.
If your answer is in a fraction, which is the usual when you start with a fraction, what you then do to finish the answer depends on what you have been taught by your teacher: some teachers prefer you to end with a whole number and a fraction: 3 4/5 but other teachers may prefer you to reduce the answer to include decimal places instead of fractions: 3.8 in this particular case.
It is minus one half.
7.5 - 0.7 = 6.8 = 6 and 4/5
1/5
It is: 3/10 = three tenths
seven and eight tenths. you have to change one half to five tenths and then add the whole numbers and then the fraction
4.70 - 3.50 = 1.20
It is minus one half.
two tenths or, simplified, one fifth.
1.85
7.5 - 0.7 = 6.8 = 6 and 4/5
either one half or five tenths both are correct
1/5
It is: 3/10 = three tenths
Negative 5 and three tenths.
Nine tenths minus four tenths is five tenths, which is also a half.
seven and eight tenths. you have to change one half to five tenths and then add the whole numbers and then the fraction
Seven and one third minus three and one half = 23/6 or 35/6
