Question

Elmer had climed most of the way up a rock wall when he slipped and fell down 2/9 of the wall. He regained his footing and climbed back up 7/10 of the wall. Write an addicting statement to match this situation.

Answer 1

1 = m - 2/9 + 7/10

Explanation:

We have to, a wall represents unity, therefore to climb a wall, it would then be 1/1 of that wall.

They tell us that the majority has risen, they do not tell us how much, therefore, we will assume that the majority with a value m.

So, when it fell, it lost 2/9 of the wall but then resumed 7/10, that is:

- (2/9) + (7/10) = -20 + 63/90 = 43/90

That is, it had an advance of 43/90 of the wall, we know that the wall is 1/1, therefore:

p = m + 43/90

m = 1/1 - 43/90 = 90-43 / 90

m = 47/90

It means that most of the wall is 47/90

The function would be

1 = m - 2/9 + 7/10
