William fills 1/3 of a water bottle in 1/15 of a minute. How much time will it take him to fill the bottle?

1/5 minutes

Step-by-step explanation:

✓Let the X= a bottle of water

✓Let y= number of minutes it will takes to fill a bottle

We can express the given statement as

1/3 X = 1/15 mins

X= ymins

If we cross multiply the two expression above we have

X/15 mins= X/3 mins * ymins

15 mins * X * y mins= 3X

Divide both sides by X

15 mins * y= 3

Make "y" the subject of the formula

y= 3/15 mins

Divide both numerator and denominator by factor of 3.

y= 1/5 minutes

Hence, the time it will take him to fill the bottle is 1/5 minutes

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
