Firstly we need to find the common denominator:

2/3 - 1/5 =
= 10/15 - 3/15 =
= 7/15

We can't simplify it so that's the result :) I hope it will help you :)

It equals 7/15 
1. find the least common multiple of the 2 denominators(bottom numbers) 
for this problem: the lcm is 15(3 times 5)
2. the fractions will now be 10/15(2/3) and 3/15(1/59
3. subtract ONLY the numerators(upper numbers)
4. 10-3=7
5. your answer will be 7/15

So 1 box is 1.5 ounces of tea.
multiply 1.5 by 112 and you get 168.
Then divided by 16 to make the ounces become pounds.

Determine whether the triangles in each pair are similar.
DerKrebs [107]

Answer:

None, they are not similar.

You can tell by trying to match ratios with others.

55:42:36

(I put them least to greatest order because triangles cannot really like change only one sides' value, so it makes it visually easier to comprehend.

8:7:5

I can't see any possible way to relate these two ratios together.

The 5 cannot go into 36 anyhow, and like the 8 and 55. The 7 can be multiplied by 6 to get 42, but 5 and 8 cannot reach their own numbers.

Step-by-step explanation:

I shall accept every question from your profile >:)
