Question

Find the value of 2/3 - 4/5 + 7/15 -11/20

Answer 1

$\frac{2}{3} - \frac{4}{5} + \frac{7}{15} - \frac{11}{20}$

$\frac{10 - 12}{15} + \frac{28 - 33}{60}$

$\frac{ - 2}{15} + \frac{ -5 }{60}$

Lcm = 60

$\frac{ - 8 - 5}{60}$

$\frac{ - 13}{60}$

Answer 2

ANSWER:-

➣

• Given:-

$\large{\frac{2}{3} - \frac{4}{5} + \frac{7}{15} - \frac{11}{20}}$

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

• SOLUTION:-

$\large{\frac{2}{3} - \frac{4}{5} + \frac{7}{15} - \frac{11}{20}}$

• Taking LCM

$\implies{\bf{LCM = 60}}$

$\large{\longrightarrow{\frac{40 - 48 + 28 - 33}{60}}}$

$\large{\longrightarrow{\frac{68 - 81}{60}}}$

$\large{\longrightarrow{\frac{-13 }{60}}}$

$\implies{\bf{\frac{ - 13}{60}}}$
