Question

Tính:

a, 3/4  * 2/9 + 1/3 =                                                  b, 1/4 : 1/3 - 1/2 =

Answer 1

a: =6/36+1/3=1/6+1/3=1/6+2/6=3/6=1/2

b: =3/4-1/2=3/4-2/4=1/4

Answer 2

\(a,\dfrac{3}{4}\times\dfrac{2}{9}+\dfrac{1}{3}=\dfrac{1}{6}+\dfrac{2}{6}=\dfrac{3}{6}=\dfrac{1}{2}\\ b,\dfrac{1}{4}:\dfrac{1}{3}-\dfrac{1}{2}=\dfrac{1}{4}\times\dfrac{3}{1}-\dfrac{2}{4}=\dfrac{3}{4}-\dfrac{2}{4}=\dfrac{1}{4}\)

Answer 3

a,34×29+13=16+26=36=12b,14:13−12=14×31−24=34−24=14
