Answer:
4.5
Step-by-step explanation:
First we need to turn the ratio of 1 : 3 into a fraction
1:3 = 1/3
Next we need to square that fraction
1 x 1 = 1
3 x 3 = 9
Then we turn those numbers into a fraction
1/9
We turn the .5 into a fraction
.5/x
And cross multiply both fraction by each other
1/9 x .5/x
1 x X = X
9 x .5 = 4.5
So
4.5 = X
Black - 10/35 (2/7)
White - 20/35 (4/7)
Grey - 5/35 (1/7)
To solve this problem we need to know the equivalence between yards and inches, that is:
1 yd = 36 inches
Therefore in 8 yd we have:
8(36) = 288
so in 8 yd we have 288 inches
So 8 yd is equal to 288 in
Carlton is incorrect because if you multiply 3 miles by the 5 weekdays, you get 15miles. If you add that to the 10miles Carlton runs over Saturday and Sunday, you end up with 25miles. Then, you multiply 25miles by 41weeks and get 1,025miles over the course of the 41 weeks.
