97×13+130×0.3

Mik đag cần gấp

Answer 1

97 x 13 + 130 x 0,3

= 97 x 13 + 13 x 3

= 13 x (97 + 3)

= 13 x 100 = 1300

Answer 2

\(97\times13+130\times0.3\)

\(=97\times13+13\times10\times0.3\)

\(=97\times13+13\times30\)

\(=13\times\left(97+30\right)\)

\(=13\times127\)

\(=1651\)

Answer 3

Sorry nha, mình nhân nhầm nên sửa lại nè

\(97\times13+130\times0.3\)

\(=97\times13+13\times10\times0.3\)

\(=97\times13+13\times3\)

\(=13\times\left(97+3\right)\)

\(=13\times100\)

\(=1300\)
