Question

Scrie operaţiile corespunzătoare pentru a afla fracţiile:

a)mai mici cu 3/10 decât 6/10;8/10;9/10;10/10

b)mai mari cu 2/9 decât 5/9;7/9;3/9;6/9




va rog multttttt​

Answer 1

Explicație:

a)6/10- 3/10= 3/10

8/10- 3/10= 5/10

9/10- 3/10= 6 /10

10/10- 3/10= 7/10

b)2/9+ 5/9= 7/9

2/9+ 7/9= 9/9

2/9+ 3/9= 5/9

2/9+ 6/9= 8/9

Answer 2

a)mai mici cu 3/10 decât 6/10;8/10;9/10;10/10

Facem scădere!

$\bf{fractia \: cu \: \frac{3}{10} mai \: mica \: decât \: \frac{a}{b}} \\ \\ \bf \boxed{\frac{a}{b} - \frac{3}{10} }$

$\bf \frac{6}{10} - \frac{3}{10} = \frac{6 - 3}{10} = \frac{3}{10} \\ \\\bf \frac{8}{10} - \frac{3}{10} = \frac{8 - 3}{10} = \frac{5}{10} {}^{(5} = \frac{1}{2} \\ \\ \bf \frac{9}{10} - \frac{3}{10} = \frac{9 - 3}{10} = \frac{6}{10} {}^{(2} = \frac{3}{5}$

$\bf\frac{10}{10} - \frac{3}{10} = \frac{10 - 3}{10} = \frac{7}{10}$

b)mai mari cu 2/9 decât 5/9;7/9;3/9;6/9

Facem adunare!

$\\ \bf{fractia \: mai \: mare \: cu \: \frac{2}{9} decat \: \frac{a}{b}} \\ \\ \bf \boxed{ \frac{a}{b} + \frac{2}{9} }$

$\bf\frac{5}{9} + \frac{2}{9} = \frac{5 + 2}{9} = \frac{7}{9}$

$\bf\frac{7}{9} + \frac{2}{9} = \frac{7 + 2}{9} = \frac{9}{9} = 1$

$\bf\frac{3}{9} + \frac{2}{9} = \frac{3 + 2}{9} = \frac{5}{9}$

$\bf\frac{6}{9} + \frac{2}{9} = \frac{6 + 2}{9} = \frac{8}{9}$
