I was collected 15.6 L of rainwater last year. This year, she collected 11.4 L. What percent decrease is that? Round your answer
Nina [5.8K]

Answer:

This is 27% decrease.

Step-by-step explanation:

The amount of rainwater collected last year was 15.6 L, and this year it was 11.4 L, this means 15.6 L-11.4 L= 4.2 L less water was collected this year than last year.

This 4.2 L is

\frac{4.2L}{15.4L}*100

percent of the amount of water collected last year. Evaluating this we get:

\frac{4.2L}{15.4L}*100=0.269*100=26.9%

Rounding to the nearest percent this is 27%.

Thus, the percent decrease in the amount of rainwater collected is 27%.

Do you think it is okay to make friends over the internet or is it too dangerous to trust what people over the internet are sayi
Lemur [1.5K]
I think it’s kind of ok only if they tell us sensible things. For example we might have some problems but we feel embarrassed to tell someone who we know so we want good advice from someone who doesn’t know me and can’t judge me based on anything other than my story and reasons. But if someone tells me we should you should refuse and if they start bothering you then you should tell an adult. Hope this helps!!!
