Answer 1

The equation is of the form,

`(78)/(100 ) =( 42)/(n)`

for the 2nd question,

(1 1/2)/100 = 15/n

Explanation:

For the 2nd one,

15 is 1 1/2% of what number

so, 1 1/2 = 3/2

so, the question is, 15 is 3/2% of what number

i.e. 15/n = (3/2)%

so, the answer should be,

(1 1/2)/100 = 15/n
