Answer:
15
Step-by-step explanation:
x/3 + 3 = 8
x/3 + 9/3 = 8
x + 9 = 24
x = 15
there are 13 people in line
Lcm=18
First do prime factorization of 6 and 9
common factor of 6 is 3
and remaining factor is 2×3
Now,
C.F×R.F= 3×2×3
=18
3.7 + r < 1.2
a number r added to 3.7 is 3.7 + r
New expression 3.7 + r should be less than 1.2 --->
