To sum two fractions, you have to transform them in order to have the same denominator: if you multiply both numerator and denominator of the first fraction by 8, and numerator and denominator of the second by 3, you have

\dfrac{2}{3} = \dfrac{2\cdot8}{3\cdot8} = \dfrac{16}{24}

\dfrac{3}{8} = \dfrac{3\cdot3}{8\cdot3} = \dfrac{9}{24}

Now we can easily sum the fractions, because we only have to sum the numerators:

\dfrac{2}{3} + \dfrac{3}{8} = \dfrac{16}{24} + \dfrac{9}{24} = \dfrac{16+9}{24} = \dfrac{25}{24}

Can you help me with this question in geometry?
Svetllana [295]
I believe this just uses the Pythagorean Theorem. A^2+B^2=C^2. So:
15^2+B^2=25^2. Simplified this is,
225+B^2=625
625-225=400
B^2=400
√ B=<span>√ 400
</span>B=20
