anthony bought an 8 foot board.He cut off 3/4 of the board to build a shelf,and gave 1/3 of the rest to his brother for an art project.How many inches long was the piece anthony gave to his brother?

Sagot :

Convert your feet to inches.
So 8 times by 12 = 96 inches
if you have 3/4 of the board used. 
3/4= .75 
if you were to times 96 by .75 = 72 inches.
So you used 72 inches and you have 24 inches left

now do 1/3= .33
times .33 by 24= 8
8 inches is how long you would give to Anthony's brother.

The length he gave to his brother = 8 inch

Further explanation

There are 7 main quantities that have been determined based on international standards, namely:

  • 1. Length, meters (m)
  • 2. Time, second (s)
  • 3. Mass, kilograms (kg)
  • 4. Temperature, kelvin (K)
  • 5. Light intensity, candela (cd)
  • 6. Electric current, ampere (A)
  • 7. Amount of substance, mol (m)

The length indicate the distance between two points in a place

The symbol is usually expressed in l, length

Length measurement can be used by several measuring instruments such as ruler / ruler, caliper length, meter, screw micrometer

The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:

  • Kilometer, km
  • Hectometer, hm
  • Dekameter, dam
  • Meter, m
  • Decimeter, dm
  • centimeter, cm
  • millimeters, mm

Each one unit descends then multiplied by 10, and if one unit increases then divided by 10

English units are the units that were used in England

For the length , the standart from English unit is yard

The conversions between units:

1 m =

a. 1.09361 yard

b. 6.214.10⁻⁴ mile

c. 3.2808 foot

d. 39.3701 inch

Anthony bought an 8 foot board

He cut off 3/4 of the board and gave 1/3 of the rest to his brother

the length of the board he cut :

[tex]{\displaystyle L = {8\:\times\frac {3} {4}}[/tex]

L cut = 6 foot

Remaining board length :

8 - 6 = 2 foot

From the length of 2 foot , he gave 1/3  to his brother, so the length of board he gave :

[tex]{\displaystyle L = {2\:\times\frac {1} {3}}[/tex]

[tex]{\displaystyle L = {\frac {2} {3}}\:foot[/tex]

we convert this to inch

1 foot = 12 inch

so for [tex]{\displaystyle L = {\frac {2} {3}}\:foot[/tex] become:

[tex]{\displaystyle L = {12\:\times\frac {2} {3}}\:inch[/tex]

The length he gave = 8 inch
