Law homework help. ##4 4/15″ miles”##
To calculate the ##color(blue)”total distance”## that Shannon walked we have to ##color(blue)”add”## the distances walked on each day.
That is : ##1 2/3+2 3/5##
One way of doing this is to add the whole numbers together and add the fractions separately.
Now ##1 2/3=1+2/3″ and ” 2 3/5=2+3/5##
##rArr1 2/3+2 3/5=1+2/3+2+3/5##
##=(1+2)+(2/3+3/5)…….. (A)##
Before adding the fractions we require them to have the ##color(blue)”same denominator”##
multiplying ##2/3″ by ” 5/5″ and ” 3/5″ by ” 3/3## will give this.
##(2/3xx5/5)+(3/5xx3/3)=10/15+9/15##
now that we have a ##color(blue)”common denominator”## we can add the numerators together.
##rArr10/15+9/15=(10+9)/15=19/15=1 4/15##
Returning to (A) we obtain the total distance Shannon walked.
That is ##3+1 4/15=3+1+4/15=4 4/15″ miles”##
