What single percentage change is equivalent to a 15% decrease followed by a 16% decrease?

Mathematics
1 answer:
Tomtit [17]2 years ago
8 0

Answer:

Decrease of 28.6%.

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

Decrease of 15%

1 - 15/100 = 1 - 0.15 = 0.85

Decrease of 16%

1 - 16/100 = 1 - 0.16 = 0.84

Both:

0.85*0.84 = 0.714

Change:

The initial percentage is 100% = 1.

0.714 - 1 = -0.286

Negative, so a decrease

The answer is a decrease of 28.6%.

If you round this answer to the nearest tens place, it would be 787592800. Since the 799 is closer to 800 rather than 790, it would round up and change the last three digits of the number instead of the usual two digits.

Hope this answer helps. Cheers.

Which ones are greater than the other
irakobra [83]

1. 0.91<0.93; 0.91 is farther away from the whole number 1 so it is less than 0.93.

2. 0.5=0.50; 0.5 and 0.50 are the same, since the decimal can be written with or without the zero.

3. 1.08<1.6; 1.08 is farther away from the whole number 2, so it is less than 1.6.

Vikki [24]

Answer:

The ratio of her savings to expenditure <u>1 : 7</u>.

Step-by-step explanation:

Given:

Neelam's annual income is Rs. 288000.

Her annual savings amount  to Rs. 36000.

Now, to get the ratio of her savings to her expenditure:

So, we get the expenditure first:

Expenditure = Income - Savings.

Expenditure = 288000 - 36000 = Rs. 252000.

Now, <em>the ratio of savings to expenditure:</em>

\frac{Savings}{Expenditure} =\frac{36000}{252000}

\frac{Savings}{Expenditure} =\frac{1}{7}

Thus, Savings:Expenditure = 1:7.

Therefore, the ratio of her savings to expenditure 1 : 7.
