Which of the following is a rational number?
densk [106]
An irrational number is a number that cannot be expressed as a fraction, like Pi
-------------------------------
The square root of 2 is irrational as it cannot be expressed as a fraction since the decimal never stops and never repeats.
Same goes for the square root of 3, and 5
-------------------------------
Square root of 1 is rational as because the square root of 1 is 1, and the number 1 can be expressed as a fraction (1/1)

Can someone please help me

1a) so for this problem, I took what they gave you, 637.5 and divided it by .75 and got 850

so .75 * 850 = the gallons, so just take the number of hours and multiply it by 850 to get your gallons

0.25 x 850 = 212.5

1.5 x 850 = 1,275

2.5 x 850 = 2,125

1b) the unit rate is 850

1c) 5.5 x 850 = 4,675 gallons

1d) So 850 gallons can be filled in an hour, you only need 100 gallons

850/100 = 17/2 (simplified)

17 gallons/hour 60 minutes

------------------------- x ---------------------

2 gallons 1 hour

the gallons cancel out and the hours cancel out which leaves us with:

17 x 60 = 1,020 / 2 = 510

510 minutes

2) I don't know how to do two sorry
