PLZ HELP 10 PTS!!
solniwko [45]

Answer:

Jill's best friend jumped 8/21 feet further than Jill.

Step-by-step explanation:

we have that

Jill jumped 6 1/3 feet

Jill best friend jumped 6 5/7 feet

To find out how much farther did Jill's best friend jumped, subtract the length that Jill jumped from the length that Jill best friend jumped

6\frac{5}{7}-6\frac{1}{3}

but first convert mixed number to improper fraction

6\frac{5}{7}\ ft=\frac{6*7+5}{7}=\frac{47}{7}\ ft

6\frac{1}{3}\ ft=\frac{6*3+1}{3}=\frac{19}{3}\ ft

substitute the values

\frac{47}{7}-\frac{19}{3}=\frac{47*3-7*19}{21}=\frac{8}{21}\ ft

therefore

Jill's best friend jumped 8/21 feet further than Jill.
