(11/10-4/11)÷15/44 даю 100 балов​

Answer 1

(11/10 - 4/11) : 15/44 = 2 4/25

1) 11/10 - 4/11 = 121/110 - 40/110 = 81/110

2) 81/110 : 15/44 = 81/110 · 44/15 = (27·2)/(5·5) = 54/25 = 2 4/25

Ответ: 2 целых 4/25 (или 2,16 в десятичных дробях).

Answer 2

To solve the expression (11/10-4/11) ÷ (15/44), we can follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

First, let's simplify the expression within the parentheses:

11/10 - 4/11 = (11 * 11)/(10 * 11) - (4 * 10)/(11 * 10) = 121/110 - 40/110 = (121 - 40)/110 = 81/110

Now, let's divide this result by 15/44:

(81/110) ÷ (15/44) = (81/110) * (44/15) = (81 * 44)/(110 * 15) = 3564/1650 = 712/330 = 356/165

Therefore, the simplified result of the expression (11/10-4/11) ÷ (15/44) is 356/165.
