Given:
A number line going from negative 2.5 to positive 2.5 in increments of 0.5.
To find:
The inequality which is true.
Solution:
Consider the number line as shown in the below figure.
We know that, on a line as we go to the left direction, the number become smaller and as we go right, the numbers become larger.
From the number line it is clear that -1.5 is on the left side of 0.5. So,
Hence, option A is incorrect.
-0.5 is on the left side of 0. So,
Hence, option B is incorrect.
-1.5 is on the left side of -0.5. So,
Hence, option C is correct.
One half is equal to 0.5.
Hence, option D is incorrect.
Answer:
Ratio of cost of a pen to cost of a ball pen is 15:7
Step-by-step explanation:
Given that:
Cost of dozen pens = ₹180
Unit rate =
Unit rate = ₹ 15 per pen
Cost of 8 ball pens = ₹ 56
Unit rate =
Unit rate = ₹7 per ball pen
Ratio of cost of a pen to cost of a ball pen,
15 : 7
Hence,
Ratio of cost of a pen to cost of a ball pen is 15:7
