  There are 6 tanks and each with 600 L of water. If 1987 L of water is used, how many litres of water will be there in 6 tanks?     

  Do you mean the water is taken equally from the six tanks, then . . .     

  6 • 600  =  3600              total water in six tanks     

  3600 – 1987  =  1613     total water left in six tanks     

  1613 / 6  =  268.833        amount in each tank if equally distributed

what is 360 divided by 1/9?     

When dividing by a fraction,

invert the divisor and multiply.     

                                                          360     

                                                         –––––   =   360 x 9   =  3240

Maricris spends 1/2 of her monthly income on food and rent, 1/4 of her income on clothing and 1/12 on entertainment. She saves the rest which is $700. What is her monthly income?     

    1 / 2  +  1 / 4  +  1 / 12  =     

   6 / 12 + 3 / 12 + 1 / 12  =  10 / 12     

                                         =    5 / 6     

   So, "the rest" is        R  =  (1 / 6) • (total)     

                                  700  =  (1 / 6) • (total)     

                                total  =  6 • 700     

                                total  =  4200

   The product of two consecutive natural numbers is greater than their sum by 155. Find these numbers     

   (X) • (X+1)  =  (X) + (X+1) + 155     

   X² + X  =  2X + 156     

   X² – X – 156  =  0     

   (X+12)(X –13)  =  0     

   X = –12   discard, neg nums aren't natural     

   X =   13     —>     X+1 =  14     

   check answer     

   13 x 14  =  182     

   13 + 14  =    27     

   subtract     155
