How many 4-inch by 4-inch squares can be cut from a rectangular piece of leather measuring 4 feet by two-thirds of a yard?

oee [108]

72 squares can be cut from a rectangular piece of leather measuring 4 feet by two-thirds of a yard

Solution:

Given, 4-inch by 4-inch squares can be cut from a rectangular piece of leather measuring 4 feet by two-thirds of a yard

Therefore,

Area of square = 4 x 4 = 16

Thus area of square to be cut is 16 square inches

Rectangular piece of leather measuring 4 feet by two-thirds of a yard

Convert feet to inches

1 feet = 12 inch

4 feet = 4 x 12 = 48 inches

Also,

1 yard = 36 inch

Given is a two-thirds of a yard

$\frac{2}{3} \times 36 = 24\ inches$

Thus area of rectangular piece of leather is:

$Area = 48 \times 24 = 1152\ square\ inches$

Total number of squares cut is given as:

$\text{Total number of squares cut} = \frac{\text{area of leather}}{\text{ area of square}}$

Thus we get,

$\text{Total number of squares cut} = \frac{1152}{16} = 72$

Thus 72 squares can be cut from a rectangular piece of leather measuring 4 feet by two-thirds of a yard

Which number is equivalent to 0.33333..(going on forever)?

klemol [59]

Suppose x = 0.333...

Then 10x = 3.333...

So 10x - x = 3.333... - 0.333..., and the repeating decimal part gets eliminated so that 9x = 3.

Then x = 3/9 = 1/3.
