Question

Sally is measuring the length her friends jump, susan jumps 1 2/3 yards. Jody jumps half the length of susans jump how many inches did jody jump?

Answer 1

For this case we have to:

Susan jumps $1 \frac {2} {3}$ yards, this is equivalent to:

$1+ \frac {2} {3} = \frac {3 * 1 + 2 * 1} {3} = \frac {5} {3}\ yards.$

If Jody jumps half, then we divide:

$\frac {\frac {5} {3}} {2} = \frac {5} {6}\ yards.$

Now, to know the inches we need to make a conversion. By definition we know that:

1 yard equals 36 inches. By rule of three we have:

$1 \ yard ----------------------------> 36 \ in\\\frac {5} {6} \ yards -----------> x$

Where "x" represents the inches that Jody jump:

$x = \frac {\frac {5} {6} * 36} {1}\\x = 30 \ in$

So, JOdy jumped 30 inches.

Answer:

30 inches

Answer 2

Answer:

30 inches

Step-by-step explanation:

(1 2/3)/ 2 = 5/6 yards

1 yard = 36 inches

36 - 6 = 30
