Question

Subtract : $5\frac{1}{3}-3\frac{3}{4}$

Answer 1

To subtract: $5\frac{1}{3}-3\frac{3}{4}$

Convert the above mixed fractions into improper fractions, we get

$5\frac{1}{3}=\frac{16}{3}$

$3\frac{3}{4}=\frac{15}{4}$

Now convert the above fractions into like fractions by obtaining L.C.M of their denominators , we get

L.C.M of $3$ and $4=12$

$\frac{16}{3}=\frac{16\times 4}{3\times 4}=\frac{64}{12}$

$\frac{15}{4}=\frac{15\times 3}{4\times 3}=\frac{45}{12}$

$5\frac{1}{3}-3\frac{3}{4}$$=\frac{64}{12}-\frac{45}{12}$

$=\frac{64-45}{12}$

$=\frac{19}{12}$

Thus,$5\frac{1}{3}-3\frac{3}{4}$ $=\frac{19}{12}$or $1\frac{7}{12}$. Answer
