5/8 + 4/5 = 9/8 1 17/40 57/40 9/13​
valina [46]

Answer:

57/40

Step-by-step explanation:

Find common denominators, note that what you do to the denominator, you must do to the numerator:

\frac{numerator}{denominator}

First, multiply 5/8 with 5 to both the numerator and denominator:

(5/8) x (5/5) = 25/40

Next, multiply 4/5 with 8 to both the numerator and denominator:

(4/5) x (8/8) = 32/40

Combine the numerators:

(25 + 32)/40 = (57)/40

57/40 is your answer.

Two years ago Carol's living expenses were $ 1200 $ 1200 per month. This year the same items cost Carol $ 1400 $ 1400 per month.
EleoNora [17]
Given:
2 years ago - consumer price index 1,200 per month
current year - consumer price index 1,400 per month

Inflation rate = [(Consumer price index current - Consumer price index previous) / Consumer price index previous ] * 100%

Inflation rate = [(1400 - 1200) / 1200] * 100%  = (200 / 1200) * 100% =  16.67%

Since 2 years has passed, the 16.67% inflation rate is good for 2 years. We simply divide the inflation rate by 2 to get the annual inflation rate.

16.66% / 2 = 8.33%

The annual inflation rate for the past two years is 8.33%
