48.25 x .20 = 9.65........................
Answer:
Sum of two rational numbers-
-10 = -5+-5
0= -5+5
15= 10+5
Step-by-step explanation:
Answer
Given,
Mass of bag = 6 Kg
Area covered by the bag = 2.5 x 5 = 12.5 m²
a) Bags required to cover area = 7.5 x 10.2
= 76.5 m²
Number of bags, N = 
N = 6.12 = 7 (approx.)
7 Bags of 6 Kg fertilizers will be needed to cover the area.
b) Cost of 6 Kg fertilizers = $15.50
Cost of 7 bags of 6 Kg fertilizers = 7 x $15.50
= $108.50.
<h3>The ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1</h3>
<em><u>Solution:</u></em>
Given that,
Five hundred sixth-grade students were surveyed
Which means,
sixth-grade students = 500
125 had traveled on an airplane
<em><u>What is the ratio of total sixth-grade students to the number of students who had traveled on an airplane?</u></em>
Therefore,
total sixth-grade students : students traveled on airplane = 500 : 125
<h3>Ratio = 500 : 125</h3>
Reduce to lowest terms,
Divide both sides by 5
<h3>Ratio = 100 : 25</h3>
Further reduce to simplest terms,
Divide both sides by 25
<h3>Ratio = 4 : 1</h3>
Thus the ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1
