Hey there!!

Let's take the first number as ' x '

Then, the second number would be ' x + 1 '

Sum of these = 183

Hence,

x + x + 1 = 183

2x + 1 = 183

2x = 182

x = \frac{182}{2}

x = 91

Hence, the small integer is 91

Hope my answer helps!

In one school, a half of all students who like math like science as well. Also, in that school, a third of all students who like
Marizza181 [45]

Answer: 2/3

Step-by-step explanation:

N is the total number of students

M is the number of students thta like math

S is the number of students that like science.

We know that half of the elements in M also are elements from S

And a third of the elements of S also are elements of M

And because those elements are common elements for both sets, we should have that:

M/2 = S/3

then we have that:

M = (2/3)*S

The ratio is 2/3

this means that the number of students that like math is 2/3 times the number of students that like science.
