10 is the answer hope that's what it was
Answer:
1/2 is equivalent to 50%
Step-by-step explanation:
In order to convert a fraction to a percentage you divide the numerator (Top number of a fraction) by the denominator (Bottom number of a fraction), multiply by 100, and add a percentage sign.
So lets try that with our first answer option A) 1/2:
1 divided by 2 = 0.5
0.5 x 100 = 50
50%
So we know that 1/2 is equivalent to 50%
2x4=8 2x2=4 4+8=12, so it is A
C. 4x + y = 21
4(3) + 9 = 21
12 + 9 = 21
21 = 21
