1/6 of an advertising catalog page is dedicated for a drawing, 5/18 for an advertisement and 1/9 for another advertisement. The rest of the page is covered with a text. Does the text cover more than half of the page?

No

Step-by-step explanation:

In other words, does the sum of 5/18, 1/9 and 1/6 exceed, equal or come out to less than 1/2?

The LCD of 5/18, 1/9 and 1/6 is 18.  Thus, these three fractions are equal to

5/18, 2/9 and 3/18, and their sum is 10/18, or 5/9.  Thus, the part of the page covered with text is 1 less 5/9, or 4/9.  No, the text does not cover more than half of the page.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
