Answer 1

after my calculation, its simply......2.8

Answer 2

Answer:

51.8 ÷ 18.5 = 2.8

Step-by-step explanation:

it is given that :

185×28=5180

we have to find the value of

51.8÷18.5

now, divide the given  185×28=5180   with '10' on both sides;

  (185×28)/10 = 5180/ 10

it results in [(185)/10] ×28  = 518

18.5 ×28 = 518

to obtain 51.8 from 518, we have to divide 518 by 10

518/10 = 51.8

so divide 18.5 ×28 = 518 by  '10' on both sides:

(18.5 ×28)/10 = 518/10

18.5×(28/10) = 51.8

18.5 ×2.8 = 51.8

now, shift '18.5' from left side to right side:

2.8 = (51.8)/(18.5)

so  51.8 ÷ 18.5 = 2.8
