Answer:

5

Explanation:

The trainer uses 75 inches of tape on 1 ankle, this can be represented in the following table:

Inches of tape ankles

75 ⇒ 1

what we need to know is how many anles can be taped with 10 meters of the tape. For that first we need to convert those 10 meters to inches

since 1 meter = 39.3701 inches

thus 10 meters = 10*39.3701inches

10 meters = 393.701 inches

If we call the unknown amount of ankes x, and we update our table we get the following :

Inches of tape ankles

75 ⇒ 1

393.701 ⇒ x

And we solve this problem by the rule of three: multiply cross quantities on the table and divide by the remaining amount like so:

x = 393.701 * 1 / 75

x= 393.701 / 75

x = 5.25

which we must round down to only 5 complete ankles.

the trainer can tape 5 ankles with the 10 meters of tape.
