Question

Answer 1

\(a,75=5^2.3\\ 150=5^2.3.2\\ =>UCLN\left(75;150\right)=5^2.3=75\\ b,\dfrac{24}{108}=\dfrac{24:12}{108:12}=\dfrac{2}{9}\\ \dfrac{80}{32}=\dfrac{80:16}{32:16}=\dfrac{5}{2}\)

Answer 2

a: ƯCLN(75;150)=75

b: 24/108=2/9

80/32=5/2

Answer 3

\(a,\)ƯCLN(75;150) = 75

\(b,\)\(\dfrac{24}{108}=\dfrac{2}{9};\dfrac{80}{32}=\dfrac{5}{2}\)

Answer 4

a)\(UCLN\left(75;150\right)=75\)
b)\(\dfrac{24}{108}=\dfrac{24:12}{108:12}=\dfrac{2}{9}\)
\(\dfrac{80}{32}=\dfrac{80:16}{32:16}=\dfrac{5}{2}\)

Answer 5

a: ƯCLN(75;150)=75

b: \(\dfrac{24}{108}\)=\(\dfrac{2}{9}\)

\(\dfrac{80}{32}\)=\(\dfrac{5}{2}\)

Answer 6

a)

có \(75=5^2.3\), \(150=5^2.3.2\)

=> \(ƯCLN\left(75;150\right)=5^2.3=75\)

B)

\(\dfrac{24}{108}=\dfrac{24:12}{180:12}=\dfrac{2}{9}\)

\(\dfrac{80}{32}=\dfrac{80:16}{32:16}=\dfrac{5}{2}\)
