There are 16 boys and 12 girls in mr..harts science class. he wants to form as many groups as possible for a project. all the groups must be the same size, with the same number of boys and the same number of girls in each group. what is the greatest number of groups mr. hart can make? how many boys and how many girls will be in each group?

12

Step-by-step explanation:there are only 12 girls so that is the only amount of groups to be formed

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the correct option is b
