Question 802128
Knowledge of place value lets you express 7.02 in expanded form as


{{{7+0*(1/10)+2(1/100)}}}
And then the simplification steps:
{{{7(100/100)+0*(10/10)+2(1/100)}}}
{{{(700+0+2)/100}}}
{{{702/100}}}
And then reduction for simplification:
divide numerator and denominator by 2,
{{{highlight(351/50)}}}
