急啊,快 给10全部QB

Answer 1

(77.4-3.096÷0.4)÷0.03
=(77.4-7.74)÷0.03
=69.66÷0.03
=2322

9.82×13-9.82×4+9.82
=9.82×(13-4+1)
=9.82×10
=98.2

Answer 2

(77.4-3.096÷0.4)÷0.03
=77.4÷0.03-3.096÷0.12
=2580-25.8
=2554.2

9.82×13-9.82×4+9.82
=9.82*（13-4+1）
=9.82*10
=98.2

Answer 3

(77.4-3.096÷0.4)÷0.03=（77.4-3.096÷0.4）×100/3
=77.4×100/3-3.096×5/2×100/3=2580-387=2193
9.82×13-9.82×4+9.82=9.82×（13-4+1）=9.82×10=98.2

Answer 4

(77.4-3.096÷0.4)÷0.03
=(77.4-7.74)÷0.03
=77.4÷0.03-7.74÷0.03
=2580-258
=2322
9.82×13-9.82×4+9.82
=9.82*(13-4+1)
=98.2
