A. 2

B. 3

C. 21⁄2

D. 31⁄2

Answer 1

Assuming that tablets can be devided,
`2(1)/(2)` tablets are needed.

Assuming that tablets cannot be devided,
`3` tablets are needed.

Explanation:

To find the total number of tablets that covers the order, we can divide the order total mg over each tablet mg.

`(TotalOrderMg)/(SingleTabletMg) = (75 mg)/(30 mg) = 2.5 mg`

• Assuming that tablets can be devided, we can express the previous result in fractions

`2.5 = (25)/(10) = (5)/(2) = (4)/(2) + (1)/(2) = 2(1)/(2)`

• Assuming that tablets cannot be devided, we need to cover 2 tables and a half, then we will need 3 tables.
