Question

A)15 7/24:3 7/20=
б)(-20 1/4)•20 5/9=
в)2 3/5:1 11/15=
г)3 1/5:(-9 3/5)=
д)11 7/13•1 23/55=
е)4 22/55•(-3 17/27)=

Answer 1

(-20 1/4)*20 5/9=-81/4*185/9=-1665/4=-416 1/4
2 3/5:1 11/15=13/5:26/15=3/2=1 1/2
3 1/5:(-9 3/5)=16/5:(-48/5)=-1/3
11 7/13 * 1 23/55 =150/13 * 78/55=180/11=16 4/11
4 22/55 * (-3 17/27)=242/55 * (-98/27)=-23716/1485=-15 1441/1485
