3%284%2F15%29+%2B+7%2F10 ...first write mixed number as a fraction

=%283%2A15%2B4%29%2F15+%2B+7%2F10

=49%2F15+%2B+7%2F10....common denominator is 30

=%282%2A49%29%2F%282%2A15%29+%2B+%283%2A7%29%2F%283%2A10%29

=98%2F30+%2B+21%2F30

=%2898+%2B+21%29%2F30

=119%2F30

=3+29%2F30

or, as decimal 3.966666666666667=>3.97
