Question

Express the fractions 3/4,7/16 and 5/8 with LCD

Answer 1

The least common multiple of the three denominators is 16 because:

$4 \times 4 = 16 \\ 16 \times 1 = 16 \\ 8 \times 2 = 16$

Change the fractions so that each fraction has a denominator of 16.

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

$\frac{7 \times 1}{16 \times 1} = \frac{7}{16}$

$\frac{5 \times 2}{8 \times 2} = \frac{10}{16}$

____________________________________________________

$1. \frac{12}{16} \\ \\ 2. \frac{7}{16} \\ \\ 3. \frac{10}{16}$
