The Four basic Mathematical Operations are:
•Addition
•Subtraction
•Multiplication
•Division
The first one is the last answer because you subtract 18 and when you divide you change the inequality symbol
the second one is the last answer for the same reason
the 3rd one is x<-1.25
the 4th one is x<8/15
1. 1 1/8= 18/16
5/16*2= 10/16
4/16*2= 8/16
9/16= 9/16
1/2= 8/16
18/16 + 10/16 + 8/16 + 9/16 + 8/16= 53/16
Simplify:
4 & 5/16sq ft
2. All you do is multiply that by 3... so 4 & 5/16 = 53/16 53/16*3 = 159/16 = 9 & 15/16 sq ft
