Simple operation method: 503 & # 178; + 1006 × 502 & # 178; - 1004 & # 178;

Simple operation method: 503 & # 178; + 1006 × 502 & # 178; - 1004 & # 178;

In order to replace (500 + 3) &\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ifthere is any mistake in the process, I will be honored,

A simple method is used to calculate (1) 165 & # 178; - 164 × 166

165²-164×166
=165^2-(165-1)(165+1)
=165^2-165^2+1
=1

How to calculate 74 times 26 + 26 times 25 + 26 in a simple way

74*26+26*25+26=26(74+25+1)=26*100=2600

The quotient of a divided by B is 1.8. What is the simplest integer ratio of a and B

The quotient of a divided by B is 1.8, and the simplest integer ratio of a and B is 9:5
1.8:1=18:10=9:5

The quotient of a divided by B is 4, and the simplest integer ratio of a to B is 4______ ．

According to the analysis, the quotient of number a divided by number B is 4, and number B is regarded as the unit "1", so the ratio of number a to number B is 4:1

The quotient of a divided by B is 1.4, and the simplest integer ratio of a and B is?

7:5

The quotient of number a divided by number B is 2.5, and the ratio of number a to number B is______ ．

The answer is: 2.5

The quotient of a divided by B is 1.4, and the simplest integer ratio of a and B is ()
I hope you can say what you mean,

A divided by B is 1.4, and the division sign is equivalent to "ratio (:)", which is also equivalent to the fractional line. Therefore, the quotient of a divided by B is the ratio of a and B, which is 1.4. Just turn it into an integer ratio
1.4=14/10=7/5

The quotient of a divided by B is 0.35. The simplest integer ratio of a and B is______ ．

Because the number of a / b = 0.35, so the number of B is 1, then the number of a is 0.35, the number of a: B = 0.35:1 = (0.35 × 100): (1 × 100) = 35:100 = 7:20; so the answer is: 7:20

The quotient of number a divided by number B is 0.35, and the simplest integer ratio of number a and number B is? Can you explain why you want to do this?

Number a △ number b = 0.35
35 = 7 / 20
therefore
The simplest integer ratio of a and B is 7:20
