2. 0.0009
3. 680
Step-by-step explanation:
Based on the ratio of boys/girls We can infer that the only possibility for Ellen's math class would be answer B. 14/21
Factor 36 and add them, make sure both are negatie
1+36=37, nope
2+18=20 nope
3+12=15,nope
4+9=13, nope
6+6=12, nope
the closest one is 20
