Answer 2

Answer:

-51/140

Step-by-step explanation:

2/5 x - 3/7 - 1/4 - 3/7 x 3/5

L.C.M of 4 and 7 is 4×7=28

(2×3)/(5×7)-(1×4)-(3×7)/28×3/5

6/35/-4-21/28×3/5

6/35/-25/28×3/5

6/35(-25×3)/(28×5)

6/35(-5×3)/(28×1)

6/35-15/28

L.C.M of 35 and 28 is 7×4×5=140

(6×4)-(15×5)/140

24-75/140

-51/140
