How many complete pieces of cable 8 3/8in in length can be cut from a 15 foot length of cable?

There are 21 complete pieces of cable inch in length  that can be cut from a 15 foot length of cable.

This question can be solved by applying unitary method

We know that

1 foot  = 12 inches

So the length of 15 foot cable in inches can be written as follows

Let here be"n" number of cable pieces that can be cut from 15 foot cable

So we can write equation (1)  which is formulated and solved as follows

So we can conclude that there are 21 complete pieces of cable inch in length  that can be cut from a 15 foot length of cable.

number of complete pieces of 67/8  cable that can be cut from a 15 foot length of cable = 21

Step-by-step explanation:

The question is asking how many 8 3/8 inches in length of a cable that can be cut from a 15 foot length of cable. we have to make the unit of measurement equal to know how many  8 3/8 inches in length of a cable that can be cut from a 15 foot length of cable. Le us convert 15 ft to inches.

1 ft = 12 inches

15 ft = ?

cross multiply

15 × 12 = 180 inches

Note 8 3/8  = 67/8 inches

To know the number of pieces 67/8 inches cable that can be cut from 180 inches cable we have to divide 180 by 67/8

Therefore,

number of pieces = 180 ÷ 67/8

number of pieces = 180 × 8/67

number of pieces = 1440/67

number of pieces = 21.492537313

number of complete pieces of 67/8  cable that can be cut from a 15 foot length of cable = 21

the answer to the expression is 83
