Question

1 1/4-5/6 помогитеееее​

Answer 1

Ответ:

$1 \frac{1}{4} - \frac{5}{6} = \frac{5}{4} - \frac{5}{6} = \frac{30 - 20}{24} = \frac{10}{24} = \frac{5}{12}$

Answer 2

1 1/4 - 5/6 = 5/4 - 5/6 = (15 - 10)/12=5/12

или же:

1 1/4 - 5/6 = 5/4 - 5/6 = (5*6 - 5*4)/(4*6)=(30-20)/(24)=10/24=(10:2)/(24:2)=5/12
