So, (2/8) ÷ (5/16)
= (2/8) × (16/5)
2/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
2/8 = (2/2) / (8/2) = 1/4
Now we have:
(1/4)×(16/5)
To multiply fractions, we simply multiply the numerators and multiply the denominators:
(1 × 16) / (4 × 5) = 16/20

g = girls in class
b= boys in class
g = 2b-1
girls + boys =26
g+b=26
substitute g = 2b-1
2b-1 +b =26
combine like terms
3b-1 =26
add 1 to each side
3b -1+1 = 26+1
3b = 27
divide each side by 3
3b/3 = 27/3
b = 9
There are 9 boys
