First make an improper fraction by multiplying the whole number in front by the denominator and then adding that product to the numerator.
So 11*5 = 55 + 4 =59. Your new fraction is that result over the old numerator (). Do the same with the second fraction: 7*2 = 14 + 1 =15 --> .
The next step is to subtract one from the other. I am not quite sure if you mean then you say "subtracted by".
Side note: Usually in math, we say:
multiplied by
subtracted from
added to
divided by
So, if you meant , then after creating the improper fractions, you need to find a common denominator for both of them. Do this by asking yourself, "What number can both 2 and 5 go into?"
For example, If I had to 6 and 5 as my denominators, I would choose my common denominator to be 30. After you have chosen that, you need to multiply the numerator by whatever number you multiplied the denominator by. So, in my example, if I have and , my two new fractions would become and . Then, I can subtract one from the other.
