Step-by-step explanation:

\frac{3}{10} -  \frac{12}{18}   +  \frac{2}{6}  \\  \\  =  \frac{3 \times 9}{10 \times 9} -  \frac{12 \times 5}{18 \times 5}   +  \frac{2 \times 15}{6 \times 15}   \\  \\  =   \frac{27}{90}  -  \frac{60}{90}  +  \frac{30}{90}  \\ \\   =  \frac{27 - 60 + 30}{90}  \\  \\  =  \frac{57 - 60}{90}  \\  \\  =   - \frac{3}{90}  \\  \\  =  -  \frac{1}{30}  \\

Marissa dug three fifths of a hole in one tenth of an hour. Find the rate<br> in holes per hour
snow_lady [41]

Answer:

Step-by-step explanation:

This might be easier to do in decimals. Let's try it.

3/5 = 0.6

1/10 = 0.1

rate = holes / hours

rate = 0.6/0.1

rate = 6 holes per hour

Try it with fractions.

rate =       \frac{\frac{3}{5} }{\frac{1}{10} }    Invert and multiply the 1/10

rate =  \frac{3}{5} *\frac{10}{1} = 30/5 = 6

It's the same answer. Pick the method that you feel most comfortable with.

Brian spends
mariarad [96]

Answer:

Brian have £105 left.

Step-by-step explanation:

Given,

Amount earned by Brian per week = £168

Fraction spent on rent = 1/8

Amount spent on rent = 1/8 x 168

Amount spent on rent = £42

Fraction spent on food = 1/8

Amount spent on food = 1/8 x 168

Amount spent on food = £21

Amount left = Amount earned - amount spent on rent - amount spent on food

Amount left = 168 - 42 - 21

Amount left = £105

Brian have £105 left.

I hope this helps you
