The sum of the numbers a and B is 275. When the number a is increased by 10 times, it is equal to the number B. when the number a is reduced to one tenth, it is ()

The sum of the numbers a and B is 275. When the number a is increased by 10 times, it is equal to the number B. when the number a is reduced to one tenth, it is ()

If the number a is increased by 10 times, it is equal to the number B
B is 10 times as much as a
A equals: 275 (1 + 10) = 25
So the number of a is reduced to one tenth of it, which is (2.5)

The sum of number a and number B is 275. When the number a is 10 times larger, it is equal to number B. when the number B is 100 times smaller, it is ()

275÷（10+1）÷100
=25÷100
=0.25

The sum of a and B is 275. The reduction of a by 10 times is equal to that of B. how much is the sum of a and B
A 250, B 25, but how

B 275 / 11 = 25
A 275-25 = 250

If the sum of a and B is 22, then the number of a is 2______ ．

The number of a is 2. So the answer is: 2

The average number of a and B is 56, a: B = 3:5, a: B = 3:5=______ , B=______ ．

56 × 2 = 112112 × 33 + 5 = 42112 × 53 + 5 = 70 answer: number a is 42, number B is 70
