How do you subtract this

Mathematics
1 answer:
Maurinko [17]2 years ago

To subtract fractions, you need to obtain a common denominator. We can achieve this, in this case, by multiplying:

(\frac{4}{4} * \frac{22}{13}) - (\frac{13}{13}*\frac{21}{4})

Simplify this:

\frac{88}{52} - \frac{286}{52}

Now we have common denominators, so we can easily just subtract the numerators, and we have the answer:

-\frac{198}{52}

Notice that this is divisible by 2:

-\frac{99}{26}

That's your answer!
