Answer:
27 x a x b
Step-by-step explanation:
You have one of the answers correct. The fraction 4/8 is equal to 1/2
Other answers are: 5/10, 10/20, and 6/12
If you reduced each of those fractions, you'd get to 1/2.
You can use a calculator to find that
4/8 = 0.5
1/2 = 0.5
5/10 = 0.5
10/20 = 0.5
6/12 = 0.5
All fractions mentioned lead to the same decimal value, so this confirms all of the fractions are equivalent to one another.
Just isolate x. First you add 16 to both sides, that makes the equation 21=3x. Then divide by 3 and x=7
