The answer is 16 3/8.
So, to find out the total weight we have to add them all up. However, since we need a common denominator to add them up, we have to change the denominator of the first two mixed fractions, 2 1/2 and 1 1/2. Since we know that 2 is a factor of 8, we know that we can use 8 as the common denominator. The third mixed fraction already has a denominator of 8 so we just have to change the denominator of, 2 1/2 and 1 1/2. To do this, we just have to multiply the numerator and denominator by 4 to get, 2 4/8 and 1 4/8. Next, we can add them all up. We first add the fraction part, 4/8 + 4/8 + 3/8, which would give us 11/8, which can be turned into 1 3/8. Finally, we just have to add the whole numbers and 1 3/8, 2 + 1 + 12 + 1 3/8, to get 16 3/8.
Comment any questions if you still need help.
Use synthetic division. Look at my attachment below for a detailed explanation. If the remainder is 0 (which it is), then it's a factor.
Answer:
15
Step-by-step explanation:
To find the common denominators for 2/3 and 1/5, just look at the denominators for both of the fractions, 3 and 5
Multiply 3 and 5, which is 15. 15 is the common denominator.
B. Irrational
because it has no exact decimal equivalent and it cannot be expressed as a fraction of two integers (

is just an estimate!)
