Question

c) Are the following numbers in proportion?
(i) 7, 42 , 5 ,30 (ii) 24, 28, 36, 48

Answer 1

Answer:

Yes and no respectively

Step-by-step explanation:

So 7:42::5:30

42×5=210 (inside)

30×7=210 (outside)

So these numbers are in proportion as 210=210

And 24:28::36:48

28×36=1008 (inside)

24×48=1152 (outside)

So these numbers are not in proportion as 1008 and 1152 are obviously not equal

Mark it as the brainliest answer....
