2 3/8 - 5/8 = ? help plzzz

i just did this in school the other day! your answer is, 1 3/8

Step-by-step explanation: ignore the whole number, then subtract 5 from 3 and because you already have a common denominator, you don't need to deal with those shenanigans.

well you can't  subtract 5 from 3 so you use the whole number and 3 becomes 8  5 from 8 is 3 so your answer is 1 3/8!

∑ᵢ⁷₌ ₁(7+8i)

Explanation:

In order to write a series in sigma notation you must:

Identify the index of summation and first value. In the equation, the index of summation would be i and the first value is assumed to be 1 due to the pattern that can be traced back. Identify the last value of n, which would be 7 in the series. This value is placed as a superscript next to or above the capital Greek letter ∑.Identify the formula for the terms. In thes case, the formula for the terms is (7+8i) because there are seven terms in the sequence that are increasing by 8. The variable i comes after because that is the letter used in the index of summation.
