4 0

Answer: room 101 and room 107

Step-by-step explanation:

In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3

In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.

In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3

Therefore, room 101 and room 107 have the same ratio.

Answer:

0.40d

d - 0.60d

Step-by-step explanation:

d - 0.60

This doesn't work because it wants 60<em><u>%</u></em> 0.60 without the percent is a decimal number, and is not 60% of d.

100% - 60% = 40%

0.40d works because it is multiplying 0.40 and d which is also 40%.

d - 0.60d works because it is multiplying 0.60 and d which is also 60% and then subtract it from d.

0.60d doesn't work because it want the discounted price not the discount.

1 - 0.60d doesn't work because we don't know that d = 1, so it is subtracting the discount from 1 not d.
