Question

4/9+11/8-5/6

Tính nhanh:

478×56+44×478

 

 

Answer 1

\(\frac{4}{9}+\frac{11}{8}-\frac{5}{6}\)

\(=\frac{71}{72}\)

478 x 56 + 44 x 478

= 478 x (56 + 44)

= 478 x 100

= 47800

Answer 2

4/9+11/8-5/6

= 131/72 - 5/6

= 71/72

Tính nhanh:

478×56+44×478

= 478 x ( 56+44 )

= 478 x 100

= 47800
