The quotient of a divided by B is 8. The sum of a and B is 720______ The number B is______ .
720 △ 8 + 1 = 720 △ 9 = 80720-80 = 640, answer: the number a is 640, the number B is 80, so the answer is: 640, 80
The sum of number a and number B is 452. The quotient of number a divided by number B is 8. What is the number B
Let B be x, then a be 452-x
Then 452-x = 8x + 2
The solution is x = 50
So the number B is 50
A's money is one fourth more than B's. after a spends 360 yuan, B is one third more than A. how many yuan did a and B have?
How many yuan is the money of Party A and Party B
Suppose B has x yuan, then a has 5x / 4 yuan
(5X/4-360)*(1+1/3)=X
5X/3-480=X
2X/3=480
X=720
A = 720 * 5 / 4 = 900 yuan
B = 720 yuan
There are 360 books in the two bookshelves, one fourth of which are taken out from bookshelf A and 60 from bookshelf B. the ratio of the remaining two bookshelves is 3:2,
How many books are there on each shelf?
It turns out that a has:
(360-60)÷[1+(1-1/4)x2/3]
=300÷3/2
=200 copies
It turns out that B has:
360-200 = 160
The sum of the three numbers of a, B and C is 360. It is known that a is three times that of B, C is four times that of B, and a is?
Let B be x, then a be 3x, C be 4x, then x + 3x + 4x = 360,
The solution is x = 45, then a = 135
The sum of the three numbers a, B and C is 360. The number a is 20 less than the number B, and the number C is 20 more than the number B. the number a is 360______ .
Let number B be x, then number a is x-20, number C is x + 20, x + x-20 + X + 20 = 360, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 3x = 360, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 120, number a is 120-20 = 100, answer: number a is 100, so the answer is: 100
The greatest common factor of two numbers is 60 and the least common multiple is 360. One of them is 120 and the other is 360______ .
360 △ 120 = 3, 60 × 3 = 180; answer: another number is 180
The greatest common factor of two numbers is 60, the least common multiple is 360, one of which is 180, the other is 360______ .
360 △ 180 = 2, 60 × 2 = 120; answer: the other number is 120
The greatest common factor of two numbers is 60 and the least common multiple is 360. One of them is 120 and the other is 360______ .
360 △ 120 = 3, 60 × 3 = 180; answer: another number is 180
Two two digit numbers, their greatest common factor is 9, the least common multiple is 360, then what is the larger number of the two digit numbers
Let these two numbers be 9a and 9b respectively, then 9ab = 360, and ab = 40. Because 40 = 1 * 40 = 2 * 20 = 4 * 10 = 5 * 8, only AB = 5 * 8 is in line with the meaning of the question. Therefore, these two numbers are 5 * 9 = 45 and 8 * 9 = 72, so the larger number is 72
