The hundreds digit and the ones digit of a three digit number are the same. The sum of its tree digits are 16. If the tens digit
tensa zangetsu [6.8K]
<h2>727</h2>

Step-by-step explanation:

       Let us denote the three digit number by abc, where a is the hundreds digit, b is the tens digit and c is the ones digit.

       Hundreds digit = a = Ones digit = c

       Sum of digits = a+b+c=16

       So, 2c+b=16

       On exchanging tens and ones digit, value increases by 45. So acb is 45 greater than abc.

       acb-abc=45

       100a+10c+b-100a-10b-c=45\\9c-9b=45\\c-b=5

       2c+b=16,c-b=5\\3c=21\\c=7=a\\b=2

∴ Required number is 727

If a girl read 3/8 of a chapter book and another girl read 3/6 of a chapter book which girl read more pages
fredd [130]

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 \frac{3}{8} \ and \ \frac{3}{6}

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

\frac{3}{8} = \frac{3*3}{3*8} =\frac{9}{24} \\\frac{3}{6} = \frac{4*3}{4*6} =\frac{12}{24}

Then compare between \frac{9}{24} \ and \frac{12}{24}  \\

So, the fraction of the great numerator will be the great fraction

\frac{12}{24}  > \frac{9}{24}

∴ \frac{3}{6} > \frac{3}{8}

==================================================

<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
