Explanation:

Answer 2

a) 32100 millimeters

c) 3,210 centimeters

d)3.21 decameters

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
