Ta có :\(\frac{16\times17-5}{16\times16+11}\)
\(=\frac{16\times\left(16+1\right)-5}{16\times16+11}\)
\(=\frac{16\times16+16-5}{16\times16+11}\)
\(=\frac{16\times16+11}{16\times16+11}\)
\(=1\)
16x 17-5/16 x 16 +11
= 16 x 17 - 16 x 5/16 + 11
= 272 - 5 + 11
= 267 + 11
= 278
bài ko ghi là tính nhanh nên mk ko tính nhanh nha
\(16.\left(17-\frac{5}{16}\right).\left(16+11\right)\)
=\(16.17.\left(17-\frac{5}{16}\right)\)
=\(272.\frac{267}{16}\)
=\(4539\)
16x17-\(\frac{5}{16}\)x16+11=16x17-5:16x16+11=16x17-5+11=272-5+11=278
tự lấy máy tính ra tính đi nhé
16 x \(\frac{17-5}{16}\)x 16 + 11
= 16 x \(\frac{12}{16}\)x 16 + 11
= 16 x \(\frac{3}{4}\)x 16 + 11
= \(\frac{48}{4}\)x 16 + 11
= 12 x 16 + 11
= 192 + 11
= 203
Chúc bạn học tốt !
\(16.17-\frac{5}{16}.16+11\)
\(=16.\left(17-\frac{5}{16}\right)+11\)
\(=16.\left(\frac{272}{16}-\frac{5}{16}\right)+11\)
\(=16.\frac{267}{16}+11\)
\(=267+11\)
\(=278\)
~ rất vui vì giúp đc bn ~ ^_<
trả lời:
\(16.7-\frac{5}{16}.16+11\)
\(=16.\left(17-\frac{5}{16}\right)+11\)
\(=16.\left(\frac{272}{16}-\frac{5}{16}\right)+11\)
\(=16.\frac{276}{16}+11\)
\(=267-11\)
\(=278\)
học tốt
\(16\text{ x }17-\frac{5}{16}\text{ x }16+11\)
\(=16\text{ x }17-5+11\)
\(=16\text{ x }17-16\)
\(=16\left(17-1\right)\)
\(=16\text{ x }16=256\)
\(16\text{ x }17-\frac{5}{16}\text{ x }16+11\)
\(=16\text{ x }\left(17-\frac{5}{16}\right)+11\)
\(=16\text{ x }\frac{267}{16}+11\)
\(=267+11\)
\(=278\)
