17,3 * 99 + 18 - 0,66
= 1712,7 + 18 - 0,66
= 1730,7 - 0,66
= 1730,04
Cho mình nha
17,3 x 99 + 18 - 0,66
trả lời
17,3 x 99 + 18 - 0,66
=1712,7+18-0,66
=1730,04
\(17,3.99+18-0,66\)
\(=1712,7+18-0,66\)
\(=1730,7-0,66\)
\(=1730,04\)
\(17,3\times99+18-0,66\)
\(=\frac{173}{10}\times99+18-\frac{33}{50}\)
\(=\frac{17127}{10}+18-\frac{33}{50}\)
\(=\frac{17307}{10}-\frac{33}{50}\)
\(=\frac{43251}{25}\)
\(=1730,04\)
