Question

(+5 1/4)*(-2 2/2)-(-4 2/10):(3 2/5)+(-6/7)*(-2 1/3)*(-3 1/4)

Comments

-2 2/2 эта дробь верно записана?

Answer 1

5 1/4*(-2 2/2)=21/4*3=63/4
-4 2/10:(3 2/5)=-42/10*5/17=-42/34
(-6/7)*(-2 1/3)=(-6/7)*(-7/3)=2
2*(-3 1/4)=2*(-13/4)=-13/2
63/4-(-42/34)=1071/68+84/68=1155/68
1155/68+(-13/2)=1155/68-442/68=713/68=10 33/68
