Solution:- Given numbers to compare are 512 and 521 .
As they are 3 digit numbers
So, we have to compare hundreds place.
But hundreds are equal in both the numbers with digit 5.
Next we have to compare tens place.
Case 1 :- 1 ten is smaller in 512 than 2 tens in 521 .
So we get the result that,
512 is smaller than 521
or <em> 512 < 521</em>
Case 2:-2 tens is greater in 521 than 1 ten in 512 .
So we get the result that,
521 is greater than 512
or <em> 521 > 512</em>
Rotation as you could rotate it 360 degrees back into its original place
The rates that are equivalent to this rate is 90 pages/hr
<h3>Rate of change</h3>
The rate is the number of pages Michael read in 1 hour.
If he read 135 pages in 1 1/2 hours then;
To determine the rate, we will have:
Divide both expressions:
135/x = 1.5/1
1.5x = 135
x = 135/1.5
x = 90
Hence the rates that are equivalent to this rate is 90 pages/hr
