49+7.49/49=49.(7+1/49=7+1/1=8/1=8
k cho mình nhé
\(\frac{49+7.49}{49}\)
\(=\frac{49\left(1+7\right)}{49}\)
\(=\frac{8}{1}=8\)
~Hok tốt~
\(\frac{49+7.49}{49}=\frac{49\left[7-1\right]}{49}=\frac{49.6}{49}=6\)
mình nhầm chút sang bài khác
kết quả bằng 56 nha bạn
có chút sai sót
\(\frac{49+7.49}{49}=\frac{49\left(1+7\right)}{49}\)
\(=\frac{8}{1}\)
\(=8\)
\(\frac{49+7.49}{49}\)
\(=\frac{49\cdot\left(1+7\right)}{49}\)
\(=8\)
\(\frac{49+7.49}{49}\)
\(=\frac{49\left(1+7\right)}{49}\)
\(=\frac{49.8}{49}\)
\(=8\)
