Б)-p+1.02g-23/25g-2.5p+1.1/8p=?

Срочно нужно !!!!!!!!!!!!!!!(=

Answer 1

A)7/12m+5/9n-1.1/2m-2/3n=(7/12m-1  1/2m)+(5/9n-2/3n)=(7/12m-3/2m)+(5/9n-2/3n)=

=(7/12m-18/12m)+(5/9n-6/9n)=-11/12m-1/9n=-(11/12m+1/9n)
Б)-p+1.02g-23/25g-2.5p+1.1/8p=(-p-2.5p+1  1/8p)+(1.02g-23/25g)=(-p- 25/10p+ 9/8p)+(102/100g-23/25g)=(-40/40p-100/40p+45/40p)+(102/100g-92/100g)=-95/40p+10/100g=

=-19/8p+1/10g=1/10g- 2 3/8p
