Using single digits and + - * / ^ ( ), find equations, to obtain on the R.H.S

(1) 13.12
(2) 90.09
(3) 122.2

----------------------------

K VENKATRAMANI

1)   6+7+ ( .8 +.4 )=  13.12* (14.2)

2) (9*8)+(9+8+1)+(1-.1)= 90.09* (90.9)

3) 2*(9*7-2)+.2=  122.2  (Correct)

------------------------------

R V RAO

1)((0.8*0.8)*8)+8=13.12  (Correct)

(2) (9*9)+9(0.3*0.3)=90.09*   (81.81)

(3)(8*9)+(6*8)+2+.02=122.2*  (122.02)

-------------------------------

M S SRINIVASAN

1). 3*4+.9+.3=13.2  (Correct)

2). 9*5*2+.09=90.09  (Correct) (.09 is not a single digit)

3). ( 4*5*6)+3-.8=122.2  (Correct)

JAYANTI MENON

(1) 13.12 = 1312/100
                     =  8×41/25
                     = 41x 2^3/5^2
Correct


(2) 90.09 = 9009/100
                     = 9 x 1001/100
                     = 9x 7x11x13/100
       =3^2×7×11+13/2^2×5^2
Incorrect.

(3) 122.2 = 611/5
                    =13×47/4
Incorrect.
