In Tina's math class, there are 12 boys and 15 girls which of the following is the ratio of boys to girls in Tina's class a. 12/17
b. 15/12
c. 12/15
d. 27/12

C. 12:15 or 12/15

Step-by-step explanation:

There are 12 boys in the class and 15 girls.

The question asks for boys to girls.

12 boys: 15 girls is the same as saying 12:15, 12/15, or 12 boys to 15 girls in Tina's class.

You have to pay attention to the order in which the question asks for because 15:12 is NOT the same thing as 12:15. (15:12 ≠ 12:15)

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
