You increase the size of a page by 30%. Then you decrease it by 30%. What is the size of the page now?

8 0

Lets use 1 to solve this problem because it is easiest to show.

Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3).

Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)

Therefore the page had a 9% reduction from its original size or is 91% of its original size.

Answer:

Smaller the size you started with

Step-by-step explanation:

Because for example 100 times .30 is 30 100+30=130 and 130 times .30 is 39 100-39=91. 100 > 91

Answer: 0%

Step-by-step explanation:

There are 5 colors of jelly beans.

Kaz ate all the green beans, so now only 80% of the jelly beans remain.

Kaz ate half of the orange pieces so now only 70% of the jelly beans remain.

Then Kaz ate half of the remaining pieces, so only 35% of the beans remain.

Current numbers: 0% green, 5% orange, 10% red, yellow, blue

Then he eats red and yellow candies in equal proportions until only 15% of the beans remain. This means that he ate 20% worth of red and yellow beans. This means that he ate all of the red and yellow beans.

Thus, there are 0% red beans left.

Answer:

4(1000) +11(100) + 24(10,000) +11(1000) = 256,100

Step-by-step explanation:

Maybe you want to add 4000 +1100 to 24(10,000) +11,000.

1 thousand = 10 hundreds, so 4000 = 40 hundreds

4000 +1100 = (40 +11) hundreds = 51 hundreds

1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands

24(10,000) +11,000 = (240 +11) thousands = 251 thousands

So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...

251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred

= 256,100
