What is 3/4- (-5 1/4) =<br><br> NEED HELP ASAP
Fantom [35]

Answer:

6

Step-by-step explanation:

\frac{3}{4} - (-5\frac{1}{4})

-5 1/4 is a mixed fraction. so we convert it into improper fraction

-5\frac{1}{4}=-\frac{5*4 +1}{4}=-\frac{21}{4}

\frac{3}{4} - (-\frac{21}{4})

negative and negative becomes positive

\frac{3}{4} +\frac{21}{4}

Both fractions have same denominators. so we can combine the numerators

\frac{3+21}{4}=\frac{24}{4}

Divide the fraction

\frac{24}{4}=6
