Question

Using appropriate property find. 2/5×(-3/7)-1/6×3/2+1/14×2/5​

Answer 1

Answer:

129/70

Step-by-step explanation:

1.multiple -3/7*1/2 ans is 2/14

2. again multiple 2/5*2/14 ans is 2/5

3.than do subtract 2/35-3/2 do LCM ans is 70 ,than 2/35*2/2=4/70 , 3/2*35/35=105/70 than subtract 4-105/70=101/70

4. than add 101/70+2/5 do LCM ans is 70, than 101/70*1/1=101/70, than 2/5*14/14=28/70 , than add 101+28/70=129/70
