5/16 : 0,125 + 1,456 : 7/25 + 9/2 * 0,8
tính hộ tớ nha
5/16: 0,125 + 1,456 : 7/25 + 9/2 x 0,8
Đây là bài tính
Cảm ơn ạ
\(\frac{5}{16}:0,125+1,456:\frac{7}{25}+\frac{9}{2}.0,8\)
\(=\frac{5}{16}:\frac{125}{1000}+\frac{1456}{1000}:\frac{7}{25}+\frac{9}{2}.\frac{8}{10}\)
\(=\frac{5}{16}.\frac{1000}{125}+\frac{1456}{1000}.\frac{25}{7}+\frac{18}{5}\)
\(=\frac{5}{2}+\frac{26}{5}+\frac{18}{5}\)
\(=\frac{25}{10}+\frac{52}{10}+\frac{36}{10}\)
\(=\frac{25+52+36}{10}=\frac{113}{10}\)
-5/16÷0,125+1,456÷7/25-4 1/2×0,8
\(-\frac{5}{16}:0,125+1,456:\frac{7}{25}-4\frac{1}{2}\cdot0,8\)
= \(-2,5+5,2-3,6\)
= -0,9
5/16 : 0,125 + 1,456 : 7/25 + 9/2 x 0,8
Đây là bài tính nhanh. Cảm ơn mn
(\(\frac{5}{16}\) : 0,125 ) + ( 1,456 : \(\frac{7}{25}\) ) +( \(\frac{9}{2}\) x 0,8 )
= 2,5 + 5,2 + 3,6
= 7,7 + 3,6
= 11,3
Tính
5/16 : 0,125 + 1,456 : 7/25 + 9/2 x 0,8
Mọi người giải nhanh cho em ah. Cảm ơn ạ
5/16 : 0,125 + 1,456 : 7/25 + 9/2 x 0,8 = 6.10832

Đáp số :..........................
\(\frac{5}{16}:0,125+1,456:\frac{7}{25}+4\frac{1}{2}\cdot0,8\)
5 / 16 :0 , 125 + 1 , 456 : 7 / 25 + 4 1/2 . 0 , 8
= 5 / 16 : 1 / 8 + 1,456 : 7 / 25 + 9 / 2 . 4 / 5
= 5 / 2 + 26 / 5 + 18 / 5
= 113 / 10
