Answer:
Options 2 and 3
Step-by-step explanation:
If there are 2 boys and 5 altogether, means there are 3 girls. The ratio of boys to girls would be 2:3.
Look at all the first and second options as fractions to make things simpler. Simplify the fractions and see which ones are equivalent to 2/3
4/10 = 2/5 FALSE
8/12 = 2/3 TRUE
Options 3, 4, and 5 are comparing boys to all students, so whatever matches the ratio 2/5 is true.
10/25 = 2/5 TRUE
20/30 = 2/3 FALSE
9/15 = 3/5 FALSE
