What is the lowest common denominator of 2/3 and 1/5?

1 Answer

Nov 14, 2016

$L C D = 3 \times 5 = 15$ $LCD = 3xx5=15$

Explanation:

$3 and 5$ $3 and 5$ do not have any factors in common (apart from 1, which does not count), so the LCD will be the product of the two numbers.

$3 \times 5 = 15$ $3 xx 5=15$

Both fractions can now be written with a denominator of 15.

$\frac{2}{3} and \frac{1}{5}$ $2/3 and 1/5$

= $\frac{10}{15} and \frac{3}{15}$ $10/15 and 3/15$
