Verified answer

а)29,3*0,45-29,3*0,55=29.3*(0.45-0.55)=29.3*(-0.1)=-2.93

б)51,7*4,4-4,4*1,7=4.4*(51.7-1.7)=4.4*50=220

в)7 4/5*4,8-1 1/2 *4,8+4,8*13 7/10 =

=4.8*(7 4\5-1 1\2+13 7\10)=4.8*(7-1+13+8\10-5\10+7\10)=4.8*(19+10\10)=

=4.8*(19+1)=4.8*20=4.8*10*2=48*2=96

а)29,3*0,45-29,3*0,55=29,3(0,45-0,55)= -2.93

б)51,7*4,4-4,4*1,7 =4,4(51,7 - 1,7)=220

в)7 4/5*4,8-1 1/2 *4,8+4,8*13 7/10 = 4,8( 7 4/5 - 1 1/2 +13 7/10)= 

4,8( 7 4/5 - 1 1/2 +13 7/10) = 4,8(7 8/10 - 1 5/10 + 13 7/10)=20*4.8=96
