hoa phượng có ăn được không?

\(\left(\dfrac{5}{2}+\dfrac{7}{12}\right)\times12\)

\(=\dfrac{5}{2}\times12+\dfrac{7}{12}\times12\)

=30+7

=37

:

\(\dfrac{19}{15}\times\dfrac{23}{14}\times\dfrac{15}{19}=\dfrac{19}{19}\times\dfrac{15}{15}\times\dfrac{23}{14}=\dfrac{23}{14}\)

:)) chả bt nhiều lắm

\(x\) + \(\frac{35}{56}\) = \(\frac78\)

\(x\) = \(\frac78\) - \(\frac{35}{56}\)

\(x\) = \(\frac{49}{56}\) - \(\frac{35}{56}\)

\(x\) = \(\frac{14}{56}\)

\(x=\frac14\)

a: \(\dfrac{32\times50}{48\times25}=\dfrac{32}{48}\times\dfrac{50}{25}=\dfrac{2}{3}\times2=\dfrac{4}{3}\)

b: \(\dfrac{56\times27}{49\times36}=\dfrac{56}{49}\times\dfrac{27}{36}=\dfrac{8}{7}\times\dfrac{3}{4}=\dfrac{3\times2}{7}=\dfrac{6}{7}\)

c: \(\dfrac{121\times42}{77\times54}=\dfrac{121}{77}\times\dfrac{42}{54}=\dfrac{11}{7}\times\dfrac{7}{9}=\dfrac{11}{9}\)

a: \(56\times89-46\times89\)

\(=89\times\left(56-46\right)\)

\(=89\times10=890\)

b: 700+197-200+203

=500+(197+203)

=500+400

=900

a) 56 x 89 - 46 x 89

= (56 x 89 - 46 x 8)

= (56 - 46) x 89

= 10 x 89

= 890

b) 700 + 197 - 200 + 203

= (700 - 200) + (197 + 203)

= 500 + 400

= 900

Tick cho tớ với ạ

đẹp

có nha, rất hay lun đó

bình thường
