You can convert 2/3 into a fraction that makes adding a lot easier.
Since 3 times 2 is equal to 6, you can multiply the numerator and denominator of 2/3 by 2 to get 4/6.
From there, you add 4/6 + 5/6 to get 9/6.
Since both 9 and 6 are divisible by 3, you can simplify the fraction to 3/2.
Your final answer would be 3/2
Which can also be formatted as 1 1/2 or 1.5
C. The answer is C because the total amount of students is 14, and there are 4 boys, which makes the ratio 4 boys to 14 students in total. 4 and 14 are both divisable by 2, so divide 4 to get 2 and divide 14 to get 7. This leaves you with 2 and 7. The ratio would be 2 boys to 7 total students. Hope this helped
PERIMETER = 2 (LENGTH + WIDTH)
PERIMETER = 2 LENGTH + 2 WIDTH
Given: Length 5 inches
P = 2(5 in) + 2w
P = 10 in + 2w
Perimeter is dependent in both length and width. Changes in any length of width will automatically change perimeter.
For find width using the perimeter formula:
P = 10 + 2w
P - 10 = 2w
(P-10)/2 = w
P/2 - 5 = w
w = P/2 - 5
If the perimeter and length is given, you can use the derived formula to solve for width.

This is the answer i hope it helps
