Answer:

55%

Step-by-step explanation:

to find percentages:

\frac{part}{whole} I \frac{percent}{100}     pretend this is a box

basically just fill this in and it will give you what you want. For example, here, you have the original and part of the original so it will look like this:

\frac{99}{180} I \frac{x}{100} then you multiply across and divide top to bottom (doesn't matter in which order), so: \frac{99}{180} =0.55 · 100 = 55%.

Last week, it rained g inches. This week, the amount of rain decreased by 5%. Which expressions represent the amount of rain tha
dybincka [34]

Answer:

The correct answers are:

0.95g

g - 0.05g

(1 - 0.05)g

Step-by-step explanation:

Amount of last week's rain = g inches

this week = 5% decrease on last week's amount

5% of last week's amount = 5/100 × g = 0.05g

∴ This week's amount of rain = 0.05g decrease

∴ Amount of rain this week = (Amount of rain last week) - 0.05g

∴ Amount of rain this week = g - 0.05g

This can be simplified by factorizing the common term "g"

g - 0.05g = g(1 - 0.05) = 0.95g
