Answer:

It takes 1 minute 12 seconds to fill the bucket if both taps are turned on.

Step-by-step explanation:

One tap fills the bucket in 2 minutes, thus fills 1/2 of the bucket in one minute.
Other tap fills the bucket in 3 minutes, thus fills 1/3 of the bucket in one minute.
Both together fill 1/2+1/3=5/6 of the bucket in one minute.
If they can fill 5/6 of the bucket in 1 minute, they fill 1/6 of the bucket in 1/5 minute.
They can fill the bucket (6/6) in 1+1/5 minute
This is 1 minute 12 seconds

just olya [345]

Answer:

$- 1 \frac{1}{10}$

Step-by-step explanation:

$- \frac{7}{10} - \frac{4}{10}$

The two fraction have the same denominator , so put them under a common denominator

$\frac{ - 7 - 4}{10}$

Simplify

-7-4=-11

$\frac{ - 11}{10} = - \frac{11}{10}$

write in mixed fraction form

$- 11 \div 10 = 1 \: remainder \: 1 \\ = - 1 \frac{1}{10}$
