The ratio would be 8/41 since the total number of students is 82. (16+66). then, the ratio of boys to all students is 16/82. then, just simplify the ratio and the answer is 8/41
Set up an equation. Since the ratio is 3:4 male:female, it would be 3m=4f. Since you know that 3m=18, solve for m and plug it into the 3m=4f equation to get the number of females! Don't forget that the number of females is 4f not just f!
Step-by-step explanation:
the answer is in the above image
Our basis would be 204 pounds. His original weight, 6 week ago, must be
204 + 2(6) = 216 pounds
But, we have to find the number of weeks having known the present weight (204 pounds) and the target weight (189). The linear equation would be

189 = 204 - 2(number of weeks)
Number of weeks = (204-189)/2
Number of weeks = 7.5
The total number of weeks would then be 6 weeks + 7.5 weeks. It would take Omar 1
3 and a half weeks since he started his diet to reach his target weight.
