Question

using appropriate properties find 1/5×(-3/2)+4/5×(-2/7)-1/6×(-2/7)
​

Answer 1

Answer:

Step-by-step explanation:

BODMAS = BRACKET, DIVIDE, MULTIPLY,  ADD, SUBTRACT

So,

= $\frac{-3}{10} - \frac{8}{35} + \frac{2}{42}$

= $\frac{-3}{10} - \frac{8}{35} + \frac{1}{21}$

= LCM = 210

= $\frac{-63 - 168 + 21} {210}$

= 210/210

= 1
