Find three consecutive odd numbers whose sum is 1875.

masya89 [10]

Answer:

smaller number = 623

middle number = 625

larger number = 627

Step-by-step explanation:

Variable: X = smallest number

If these numbers are consecutive and odd, then the numbers would be:

x, x+2, x+4

x + (x + 2) + (x + 4)= 1875

3x + 6 = 1875

3x = 1869

x = 623

x + 2 = 625

x + 4 = 627

Check:

623 + 625 + 627 = 1875

Which statement is true? A.27/19<11/30 B.17/31>19/14 C.16/26>30/31 D.35/30<22/12

Mrac [35]

A. $\frac{27}{19}$

To find greater than or smaller than relation, we multiply the terms like (numerator of L.H.S with denominator of R.H.S and put the value on the left side. Then multiply the denominator of L.H.S with numerator of R.H.S and put the value on right side. Now compare the digits.)

So, solving A, we get 810<209 ... This is false

B. $\frac{17}{31}>\frac{19}{14}$
