Question 1021998
I'll do one, follow my lead.
Count the numbers after the decimal point.
Multiply by the power of 10 equal to that number.
7.24
2 numbers past, {{{10^2=100}}}.
Then simplify.
{{{7.24(100/100)=724/100=181/25}}}
.
.
.
For a mixed number, just multiply the decimal portion.
{{{7.24=7+0.24(100/100)=7+24/100=7+6/25=7&6/25}}}
