What's the largest fraction in each group? a. 5⁄6 and 29⁄36 b. 5⁄12 and 3⁄8 c. 2⁄5 and 19⁄45 d. 5⁄7, 13⁄14, and 19⁄21

Solution :

We have to find the largest fraction in each group.

a). and

     →  when we divide the number 5 with 6, we get 0.833

    → when we divide 29 by 36, we get the value 0.805

Therefore, in this group, is the largest fraction.

b).   and

       →  when we divide the number 5 with 12, we get 0.416

    → when we divide 3 by 8, we get the value 0.375

Therefore, in this group, is the largest fraction.

c).   and

      →  when we divide the number 2 with 5, we get 0.40

    → when we divide 19 by 45, we get the value 0.42

Therefore, in this group, is the largest fraction.

d).  , and  

      →  when we divide the number 5 with 7, we get 0.714

    → when we divide 13 by 14, we get the value 0.928

     → when we divide 19 by 21, we get the value 0.904

Therefore, in this group,  is the largest fraction.

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

radha is now 5 years old

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.
