Answer 1

$\huge{\texttt{SOLUTION:-}}$

1)CHANGE RECURRING DECIMALS TO FRACTIONS:-

a) 0.5 = 5/10

b) 1.2 = 12/10

c) 0.15=15/100

d) 0.24= 24/100

☆The thing you should rememner while writing in fractional form is checking the decimal places properly. If the numbers after a point is 1 then it will be /10 if 2 numbers then, /100 and if 3 are there /1000.

2)FIND THE MEAN OF THE FOLLOWING :-

☆FIRSTLY , WHAT'S THE FORMULA FOR FINDING MEAN ?

☆THE FORMULA IS =》

SUM OF ALL THE GIVEN VALUES / NUMBER OF GIVEN VALUES

a) 30+35+32+45+42+42+38+44+36+50/10

=394/10

=39.4

b)40+43+39+36+34+34+30+41+51

=348/9

=38.67 {Approximately}

c) 21+24+27+29+29+32+33+29+29+35

=288/10

=28.8

ALL THIS MEAN PROBLEMS CAN BE DONE BY USING A SINGLE FORMULA THAT IS GIVEN ABOVE.
