Question

A printer cartridge with 3 4 ⁄5 milliliters of ink will print off 1 ⁄3 of a box of paper. How many milliliters of ink will it take to print an entire box?

Answer 1

• Answer:

11 2/5 mm³

• Explanation:

Hi there !

3 4/5mm³ = (3×5 + 4)/5 = (15 + 4)/5 = 19/5 mm³

19/5 mm³ ............. 1/3 box

x mm³ .......................1 box

x = 19/5×1 : 1/3

= 19/5 × 3/1

= 19×3/5

= 57/5

= 11 2/5 mm³

Good luck !
