Question

15 supra 11 × 2 supra 3 × 22 supra 5=
35 supra 33 ÷ 5 supra 11÷ 7 supra 3
13 supra 9 + 5 supra 6 × 8 supra 3 ​

Answer 1

Salut! :)

15/11 × 2/3 × 22/5 =

( 11 se reduce cu 22, 15 cu 5 )

3 × 2/3 × 2 =

( 3 se reduce cu 3 )

2 × 2 = 4

35/33 : 5/11 : 7/3 =

35/33 × 11/5 × 3/7 =

( 33 se reduce cu 11, 35 cu 5 )

7/3 × 3/7 = ( 7 × 3 )/( 3 × 7 ) = 1

13/9 + 5/6 × 8/3 =

13/9 + 5/3 × 4/3 =

13/9 + 20/9 = 33/9

Answer 2

Explicație pas cu pas:

ღSalutare!ღ

$\frac{15}{11} \times \frac{2}{3} \times \frac{22}{5} = \frac{15 \times 2 \times 22}{11 \times 3 \times 5} = \frac{660}{165} = 660 \div 165 = \red{4}$

$\frac{35}{33} \div \frac{5}{11} \div \frac{7}{3} = \frac{35}{33} \times \frac{11}{5} \times \frac{3}{7} = \frac{35 \times 11}{33 \times 5} \times \frac{3}{7} = \frac{385}{165} \times \frac{3}{7} = \frac{385 \times 3}{165 \times 7} = \frac{1155}{1155} = \red{1}$

$\frac{13}{9} + \frac{5}{6} \times \frac{8}{3} = \frac{13}{9} + \frac{5 \times 8}{6 \times 3} = ^{2)} \frac{13}{9} + \frac{40}{18} = \frac{26}{18} + \frac{40}{18} = \frac{26 + 40}{18} = \frac{66}{18} ^{(2} = \frac{33}{9} ^{(3} = \red{ \frac{11}{3}}$

Succes!;)
