tressa's home is 4/5 mile from school. anton's home is 3/5 mile from school. how many times the distance from anton's home to sc
WINSTONCH [101]

The distance from Tressa's home to school is 1\frac{1}{3} times the distance from Anton's home to school

From the question,

Tressa's home is 4/5 mile from school

and Anton's home is 3/5 mile from school.

To determine how many times the distance from Anton's home to school is the distance from Tressa's home to school, we will divide the distance from Tressa's home to school by the distance from Anton's home to school

That is, 4/5 mile ÷ 3/5 mile

∴ we get

\frac{4}{5} \div \frac{3}{5}

= \frac{4}{5} \times \frac{5}{3}

= \frac{4}{3}

=1 \frac{1}{3}

Hence, the distance from Tressa's home to school is 1\frac{1}{3} times the distance from Anton's home to school
