<h2>727</h2>
Step-by-step explanation:
Let us denote the three digit number by
, where
is the hundreds digit,
is the tens digit and
is the ones digit.
Hundreds digit =
= Ones digit = 
Sum of digits = 
So, 
On exchanging tens and ones digit, value increases by 45. So
is 45 greater than
.



∴ Required number is 727
Answer:
163/20 or 8.15
Step-by-step explanation:
well we are going to do PEMDAS
parentheses
exponents
multiplication/ division
addition/ subtraction
2 + 2/5 x 23/4 (i made the fractions into decimals)
2 + 6.15
163/20 or 8.15
Answer:
The girl which read 3/6 of a chapter book read more pages than the other girl.
Step-by-step explanation:
We need to compare between
so, the denominator of both fractions should be the same number
Factor of 6 = 1 * 2 * * 3
Factor of 8 = 1 * 2 * 2 * 2
-------------------------------------------
The common denominator = 1 * 2 * 2 * 2 * 3 = 24

Then compare between 
So, the fraction of the great numerator will be the great fraction

∴ 
==================================================
<u>Another solution:</u>
Convert both fractions to decimal:
3/8 = 0.375
3/6 = 0.5
0.5 > 0.375
===================================================
<u>Third Solution: </u>
As the numerators are equal
The fraction of least denominator is the great fraction
So, 3/6 > 3/8
Answer:
If the slashes mean divisions and the x means multiplication, the answer would be 25a²/4/5
