Question

What number must be subtracted from each of the numbers 27,38,7,8 so that the remainder are in proportion ​

Answer 1

Step-by-step explanation:

27, 38, 7, 8

Let x be subtracted (27−x), (38−x), (7−x), (8−x)

So

(27−x)(7−x)=(38−x)(8−x)

189−27x−7x+x

2

=304−38x−8x+x

2

189−34x=304−46x

46x−34x=304−189

12x=115

x=

12

115

x=9.58

Answer 2

Answer:

27, 38, 7, 8

Let x be subtracted (27−x), (38−x), (7−x), (8−x)

So

(27−x)(7−x)=(38−x)(8−x)

189−27x−7x+x2=304−38x−8x+x2

189−34x=304−46x

46x−34x=304−189

12x=115

x=115/12

x=9.58
