\(111\cdot113+2=12545\)

\(111\cdot111+113=12434\)

\(\frac{111.113+2}{111.111+113}=\frac{111.111+2.111+2}{111.111+113}=\frac{224}{113}\)

= v = sai rồi. xin lỗi 

Ta có:

a=3.026787138

b=2.0000(804375

->a>b

112.113+2=12656+2=12658

111.111+113=12321+113=12434

Nho click cho mk nha!!!!

112 * 113 + 2 = 12656 + 2 = 12658.

111 * 111 + 113 = 12321 + 113 = 12434

\(=\dfrac{1}{110}\times\dfrac{1}{1}\times\dfrac{1}{1}\times\dfrac{114}{1}\times\dfrac{55}{57}\\ =\dfrac{114\times55}{110\times57}\\ =\dfrac{2\times1}{2\times1}=\dfrac{2}{2}=1\)

\(\dfrac{111}{110}\times\dfrac{112}{111}\times\dfrac{113}{112}\times\dfrac{114}{113}\times\dfrac{55}{57}=\dfrac{111\times112\times113\times114}{110\times111\times112\times113}\times\dfrac{55}{57}\)

                                                   \(=\dfrac{114}{110}\times\dfrac{55}{57}=\dfrac{57}{55}\times\dfrac{55}{57}=1\)

câu hỏi đâu

Khoảng cách giữa hai số hạng liền nhau là:

113-111=2(đơn vị)

Số số hạng trong tổng trên bằng:

(333-111):2+1=112(số hạng)

Tổng trên bằng:

(333+111):2x11224864

Đáp số: 24864

bằng 690

111+113+115+119+117+115

=690

111+113+115+119+117+115

=(111+119)+(113+117)+(115+115)

=230+230+230

=690

\(\text{-567-(-113)+(-69)-(113-567)}\)

=\(-567+113-69-113+567\)

=\(\left(-567+567\right)\left(113-113\right)-69\)

=\(-69\)

\(\text{15.(17-111)-17.(22+15)}\)

\(=225-1665-3774-225\)

\(=\)\(\left(225-225\right)-\left(1665+3774\right)\)

\(=0-5439=-5439\)

\(2011+\left\{743-\left[2011-\left(275\right)\right]\right\}\)

\(=2011+\left\{743-\left[2011-275\right]\right\}\)

\(=2011+\left\{743-1754\right\}\)

\(=2011-1011\)

\(=1000\)

\(x+110+x+111+x+112=x+113+x+114\)

\(\Leftrightarrow3x+333=2x+227\)

\(\Leftrightarrow3x-2x=227-333\)

\(\Leftrightarrow x=-106\)

       Vậy \(x=-106\)
