In a division formula without remainder, the sum of divisor and divisor is 200, the quotient is 4, what is the divisor?
Divisor: 200 (1 + 4) = 40
Divisor: 200-40 = 160
In division without remainder, the sum of divisor and divisor is 35.5, the quotient is 4, what is the divisor and what is the divisor?
The divisor is 35.5 (4 + 1) = 7.1
The divisor is 7.1 × 4 = 28.4
In division without remainder, the divisor + divisor × quotient = 174, the divisor is______ ．
Because the divisor = divisor × quotient, so the divisor is 174 △ 2 = 87, so the answer is: 87
If A-B = 0.5, then the value of - 3 (B-A) is
It's all
-3(b-a)=3(a-b)=1.5
The first is to use inequality to express "the difference between 2 times of a and 3 is not negative"
It's no use relying on the answers
