Answer:
the answer is -0.21 I hope that it helped you
Step-by-step explanation:
lcm of 5 and 15 is 15
15divided by 5 is three so -13 ×3 is -39 and 15÷15 is 1 so 11× 1 is 11 hence -39+11/15 is -28/15 ((+)+(-)= substraction sign whose digit is greater)
now -63 × -5 is 315((-)+(-)= addition sign +) and 25 ×7 is 175 so -28/15 ÷ 315/175 is -0.21
