Order from least to greatest: 2/3, 25%, 3/5, 0.40

Answers

Answer:

25%,0.40,(3)/(5), (2)/(3)

Step-by-step explanation:

(2)/(3), 25%, (3)/(5), 0.40

25% , to remove % we divide by 100

25% is 25/100 = 0.25

(2)/(3) is equal to 0.666

(3)/(5) is equal to 0.6

We write the numbers in decimal form

0.666, 0.25, 0.6, 0.40

Now we arrange the numbers in order

0.25, 0.40, 0.6, 0.666

So the order becomes

25%,0.40,(3)/(5), (2)/(3)
Converting everything into percents make it a lot easier.
2/3 = 67%
25% = 25%
3/5 = 60%
0.40 = 40%

Now you can order away!
25%, 0.40, 3/5, 2/3

Math vocab again : the product of a number and its Blank is one

Answers

If you multiply a number and its inverse, you get one. To obtain an inverse, you divide 1 by the number. 0 doesn't have an inverse, because you cannot divide by 0.
Multiply by the reciprocal. (Flip fraction) so the reciprocal of 3 is 1/3 (because 3= 3/1)

The current in a stream moves at a speed of 4 mph. A boat travels 5 miles upstream and 13 miles downstream in a total time of 2 hours. What is the speed of the boat in still water?

Answers

I believe it is 4.5mph because traveling upstream and the stream moves at a speed of 4mph would knock off 4 of the original number so if you add 4miles to the given 5 miles you get 9

The same is with the boat going downstream it is adding 4 miles to the original number so you subtract 13 and 4 and you get 9

If it took 2 hours to do that then you divide 9 by 2 and get 4.5
