Step-by-step explanation:
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
Step-by-step explanation:
what is the condition of loss ?1)sp>mp 2)CP>sp 3) sp>CP 4)mp>sp
Divide I from both sides then subtract r from both sides, too so in the end:
R= (E-r)/I
