If the weight of 12 sheets of thick paper is 40 gm, how many sheets
of the same paper would weigh 2 ½ kg?

40 ÷ 12=3 ⅓

2 ½ kg=2500 gm

2500 ÷ 3 ⅓=2500 × 3 ÷ 10=750 gm

750 gm

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
