Answer:
7 3/6
Step-by-step explanation:
45/6=7 ---- finding what it is divisable by
7*6=42
45-42=3 ----- finding the remainder
Set up the equation by writing the number of students in the ratio as a fraction:
3/4= (245-x)/x Cross multiply:
3x= 4(245-x) Multiply on right:
3x= 980-4x Add 4x on both sides:
7x= 980 Divide both sides by 7:
x= 140 this is how many girls there are. And:
245-140= 105= boys
