Question

simplify
2upon5 * -3upon7 -1upon14 -3upon7 *3upon5​

Answer 1

Answer:

Step-by-step explanation:

given

=$\frac{2}{5}(-\frac{3}{7}) -\frac{1}{14} - \frac{3}{7}X\frac{3}{5}$

first, we multiply according to BODMAS rule

=$\frac{-6}{35} -\frac{1}{14} - \frac{9}{35}$

Taking L.C.M. of Numerator (35,14)=70

rewrite expression as

=$\frac{-6X2}{35X2} -\frac{1X5}{14X5} - \frac{9X2}{35X2}$

=$\frac{-12}{70} -\frac{5}{70} - \frac{18}{70}$

solving

=$\frac{-12-5-18}{70}$

= -$\frac{35}{70}$

=$-\frac{1}{2}$            answer
