Which measurements are equal to 321 decimeters? Check all that apply.

a. 32,100 millimeters

b. 0.321 kilometers

c. 3,210 centimeters

d. 3.21 decameters

e. 32.1 hectometers

a) 32100 millimeters

c) 3,210 centimeters

d) 3.21 decameters

Step-by-step explanation:

To find which measurements are equal 321 decimeters, we will follow the steps below:

changing 321 decimeters to millimeters

let x be 321 decimeters in millimeters

1 decimeter = 100 millimeters

321 decimeters = x

cross - multiply

x = 321 * 100

x = 32100 millimeters

hence, 321 decimeters = 32100 millimeters

converting 321 decimeters to centimeters

let y be 321 decimeters in centimeters

1 decimeters = 10 centimeters

321 decimeters = y

cross-multiply

y = 321 * 10

y = 3210 centimeters

Thus, 321 decimeters = 3210 centimeters

converting decimeter to decameters

let z represent 321 decimeters in decameters

1 decameter = 100 decimeter

z = 321 decimeter

cross-multiply

100 z = 321

divide both-side by 100

100z/100 = 321/100

z=3.21 decameters

therefore, 321 decimeters = 3.21 decameters
