Question 1208321
<pre>

{{{(1&1/2)*(3&1/6)+(1&1/2)*(2&5/8)}}}

Change to improper fractions:

{{{(3/2)(19/6)+(3/2)(21/8)}}}

{{{57/12+63/16}}}

Reduce {{{57/12}}} to {{{19/4}}} by dividing top and bottom by 3
or you could have canceled in the preceding step.

{{{19/4+63/16}}}

The least common denominator of 4 and 16 is 16

Make the denominator in the first fraction become 16,
by multiplying by 4/4

{{{expr(19/4)expr(4/4)+63/16}}}

{{{76/16+63/16}}}

{{{139/16}}}

   <u>  8</u>
16)139
   <u>128</u>
    11

Answer {{{matrix(1,2,8&11/16,gallons)}}}
