Estimate the sum of 299 and 388

Answers

For this case we have the following numbers:

299

388

Let's round up each of the numbers to the nearest hundred,

We have then:

299 = 300

388 = 400

We note that now we have two numbers whose approximation is easier to add.

We have then:

300 + 400 = 700

Answer:

The sum of 299 + 388 is approximately:

700

An estimate of the sum 299 + 388 would be 300 + 400. The answer is therefore around 700.

What is the percent decrease from 60 to 39?

Answers

Answer: 35%

Step-by-step explanation: To find the percent decrease, we use the following formula.

$(Amount-of-change)/(original-number)$

The amount of change is the difference between the two numbers which in this case is 60 - 39 and the first number is 60.

$(60 - 39)/(60)$

60 - 39 is 21 so we are left with 21/60.

60 divided into 21 .35 times. However, our problem is asking for the percent which means we can move the decimal point two places to the right to get 35.

Therefore, the percent decrease is 35%.

$That\ is\ a\ decrease\ of\ \boxed{35}\ percent.$
