2/3 minus 5/8<br> what’s the answer

Rama09 [41]

Hey there!

$\frac{2}{3}$ $-$ $\frac{5}{8}$
Change the " $subtract$ " symbol to a $addition$ symbol
$\frac{2}{3} + \frac{-5}{8}$
$(-5)(3)$ $= -15$
$2(8)$ $=16$
$3$ $(8)$ $=$ $24$
$\frac{16}{24} + \frac{-15}{24}$
Add " $16 + (-15)$ " together
$\frac{16+ (-15)}{24}$
$16 + (-15)$ $= 1$
$24$ $= 24$
Therefore, $\boxed{Answer: \frac{1}{24} }$

Good luck on your assignment and enjoy your day!
