Question

(3 целых 4/11 * 4 целых 9/91) * 11/37=

Answer 1

4. 9/91

Пошаговое объяснение:

1) 3. 4/11 * 4. 9/91 = 37/11 * 373/91 = 13801/1001

2) 13801/1001 * 11/37 = 373/91 * 1/1 =373/91 = 4. 9/91

Answer 2

Будет $4\frac{9}{91}$

Пошаговое объяснение:

$(3\frac{4}{11} \times4\frac{9}{91} )\times\frac{11}{37} =(\frac{3\times11+4}{11} \times\frac{4\times91+9}{91} )\times\frac{11}{37}= \\ \\ =(\frac{33+4}{11} \times\frac{364+9}{91} )\times\frac{11}{37} = (\frac{37}{11} \times\frac{373}{91} )\times\frac{11}{37} =\\ \\ =\frac{37\times373}{11\times91} \times\frac{11}{37} =\frac{13801}{1001} \times\frac{11}{37} =\frac{13801\times11}{1001\times37}=\\ \\ =\frac{151811}{37037} =\frac{373}{91} =\frac{4\times91+9}{91} =4\frac{9}{91}$
