How to determine the values</h3>
It is important to note that a percentage is the number or ratio expressed as a fraction of 100.
It is denoted using the percent sign, "%"
a. What number is 53% of 43
= 53/ 100 × 43
= 0. 53 × 43
= 22. 79
b. 43% of 300
= 43/ 100 × 300
= 129
c. 12% of what number is 43
12/ 100 × x = 43
x = 43 × 100/ 12
x = 358. 3
d. 43 is what percent of 106
43/106 × 100/ 1
4300×/ 106
40. 5%
e. What percent of 43 is 6
43/ 100 × 6
2.58%
Thus, the percentage of a value is that value divided by 100

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.
