Answer:
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:
<u>changing 321 decimeters to millimeters</u>
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
<u>converting 321 decimeters to centimeters</u>
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
<u>converting decimeter to decameters</u>
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

Answer:
Basicallly, if the machine packs 2/3 of a box every 1/2 min, then the machine will pack twice as many boxes for 1 min, since 1/2 multiplied with 2 is 1.
2/3 multiplied with 2 is 4/3.
Therefore, the machine can pack 4/3 boxes per minute.
