Step-by-step explanation:
1. 4 3/4=19/4
53/2=13/2
the total change of square will be. 19/4 + 13/2= 19+26/4=45/4
2. total change is 0.7+0.4=1.1
3.-7 1/6= -43/6
3 5/6= 23/6
-43/6 + 23/6 =-20/6 = -10/3
4. metals=2.625(m)
paper=5.58(p)
glass= x
total = 9.5(t)
m + p + x = t
2.625 + 5.58 + x =9.5
8.205 + x = 9.5
x = 9.5 - 8.205
x = 1.295
