Answer:
11/20
3/5
7/10
13/20
Step-by-step explanation:
A rational number is a number that can be derived by dividing 2 whole numbers
1/2 = 0.5 0r 50%
3/4 = 0.75 75%
Between 50% and 75% are 51 - 74 which can be expressed as rational numbers
3/5 = 0.6
7/10 = 0.7
11/20 = 0.55
13/20 = 0.65
109
2a2b-6ab2+9ab+5 is right answer
$69.60
20% of $58 is $11.60. So you add $11.60 + 58 which equals $69.60, so that is the total cost.
