Question

5,3:25%+5,3*7-5,3

 

 

Answer 1

\(5,3\div25\%+5,3\times7-5,3 \)

\(=5,3\div\dfrac{25}{100}+5,3\times7-5,3\)

\(=5,3\div\dfrac{1}{4}+5,3\times7-5,3\)

\(=5,3\times4+5,3\times7-5,3\times1\)

\(=5,3\times\left(7+4+1\right)\)

\(=5,3\times10\)

\(=53\)

Answer 2

   5,3: 25% + 5,3 \(\times\) 7 - 5,3

= 5,3 \(\times\) 4 + 5,3 \(\times\) 7 - 5,3 \(\times\) 1

= 5,3 \(\times\) ( 4 + 7 - 1)

= 5,3 \(\times\) ( 11 - 1)

= 5,3 \(\times\) 10

= 53
