Answer: -4.5
Step-by-step explanation:
60% decimal = .6 fraction= 6/10
3/4 percent =75% (think of $$) decimal =.75
0.23 percent =23% fraction= 23/100
1/8 percent= 12.5 decimal = 0.125
18% decimal= .18 fraction= 18/100 (simplified to 9/50)
2/3 percent=0.6% repeating (so put a line over 6) decimal= 0.6 repeating aswell so do the same as last
Your welcome :)
Answer:
60 square units
Step-by-step explanation:
Area = length * width
First, you will need to divide the shape into two different shapes. One shape will be larger than the other.
<u>Area of large shape:</u>
A = 12 * 4
A = 48
<u>Area of small shape:</u>
A = 6 * 2
A = 12
Area = 48 + 12 = 60 sq units
