A = \(\frac{54.107-53}{53.107+54}\) và B = \(\frac{135.269-133}{134.269+135}\)
so sánh A=54.107-53/53.107+54 và B=135.269-133/134.269+135
so sánh
A=54.107-53/53.107+54 và B=135.269-133/134.269+135
A<B . K CHO MÌNH NHA
So sánh
A= 54.107-53/53.107+54
B= 135.269-133/134.269+135
so sánh 2 phân số sau
A=\(\frac{54.107-53}{53.107+54}vaB=\frac{135.269-133}{134.269+135}\)
\(A=\frac{54\cdot107-53}{53\cdot107+54}=\frac{\left(53+1\right)107-53}{53\cdot107+54}=\frac{53\cdot107+107-53}{53\cdot107+54}=\frac{53\cdot107+54}{53\cdot107+54}=1\)
\(B=\frac{135\cdot268-133}{134\cdot269+135}=\frac{\left(134+1\right)\cdot268-133}{134\cdot269+135}=\frac{134\cdot268+268-133}{34\cdot269+135}=\frac{134\cdot268+135}{134\cdot269+135}=1\)
Vì 1=1 nên A=B

So sánh
A = \(\frac{54.107-53}{53.107+54}\) Và B = \(\frac{135.269-133}{134.269+135}\)
So sanh phan so:
a)54.107-53/53.107+54=A
B=135.269-133/134.269+135
Ta thấy :
A=\(\frac{54.107-53}{53.107+54}=\frac{53.107+107-53}{53.107+54}=\frac{53.107+54}{53.107+54}=1\)
B=\(\frac{135.269-133}{134.269+135}=\frac{134.269+269-133}{134.269+135}=\frac{134.269+136}{134.269+135}>1\)
Vậy A < B
Bai 1 so sanh
\(a=\frac{54.107-53}{53.107+54}\)
\(b=\frac{135.269-133}{134.269+135}\)
\(A=\frac{54.107-53}{53.107+54}=\frac{53.107+107-53}{53.107+54}=\frac{53.107+54}{53.107+54}=1\)
\(B=\frac{135.269-133}{134.269+135}=\frac{134.269+269-133}{134.269+135}=\frac{134.269+136}{134.269+135}>1\)
Vậy A > B
So sanh:
\(\frac{54.107-53}{53.107+54}\) và \(\frac{135.269-133}{134.269+135}\)
