Question
Find the difference: $3\frac{5}{8}-2\frac{5}{12}$
✓
Answer
$3\frac{5}{8}-2\frac{5}{12}$ $=\frac{29}{8}-\frac{29}{12}$
$L.C.M$ of $8$ and $12 = (2 \times 2 \times 2 \times 3) = 24$ $=\frac{(87-58)}{24}$ $=\frac{29}{24}$
$=1\frac{5}{24}$ $\Big(\frac{24}{8}=3,3\times29=87\Big)$ and $\Big(\frac{24}{12}=2,2\times29=58\Big)$
$L.C.M$ of $8$ and $12 = (2 \times 2 \times 2 \times 3) = 24$ $=\frac{(87-58)}{24}$ $=\frac{29}{24}$
$=1\frac{5}{24}$ $\Big(\frac{24}{8}=3,3\times29=87\Big)$ and $\Big(\frac{24}{12}=2,2\times29=58\Big)$
