In a ratio, the quotient of the product of two internal terms divided by the product of two external terms is 1, right,
The inner product is equal to the outer product
So quotient is 1 correct
The quotient of the product of two external terms of a proportion divided by the product of two internal terms is 1
Right or wrong
To the theorem: the inner product is equal to the outer product
According to the following equation, arrange the four numbers a.b.c.d (ABCD is not zero) in descending order
A × 5 / 6 = B × 3 / 2 = C × 4 / 5 = D × 3 / 8
a＜c＜b＜d
We know that a = 1 / 2 of X, B = 2 / 4 of the square of X, C = x + 2 of X. we combine them into (a-b) divided by C or A-B divided by C
Please choose any one of them for calculation, first simplify and then evaluate, where x = 3
a-b/c=1/(x-2) - [2/(x+2)(x-2)] / [x/(x+2)]
=1/(x-2) - 2/[(x-2)x]
=(x-2)/[(x-2)x]
=1/x
When x = 3, 1 / x = 1 / 3
If a = negative 3.14 divided by 3.13 divided by 3.12, B = 2.14 divided by negative 2.13 divided by 2.12, C = 1.14 divided by 1.13 divided by negative 1.13, the order of ABC is?
A>B>C
It is known that a divided by a quarter, B, C divided by a thirteenth, they are equal, and a, B, C are greater than 0. Please arrange a, B, C in the order from small to large
B is greater than a is greater than C, a divided by one fourth is equal to 4a, C divided by one thirteenth is equal to 13C, so 4a is equal to B is equal to 13C, so B is greater than a is greater than C
It is known that a △ 14 = B △ 1 = C △ 113, and a, B, C are all greater than 0. Please arrange a, B, C in the order from large to small______ ．
Because quotient is equal, divisor 1 ＞ 14 ＞ 113, so divisor B ＞ a ＞ C
A times 1.1 = B times 0.9 = C divided by 1, ABC from large to small
B＞C＞A
If ABC is a different natural number, and C of a divided by B is less than a and a divided by B, then the correct conclusion is (). A is greater than C
B is less than C, a is greater than B, C is less than B
B is less than C
4A = B (a, B are not zero natural numbers), what is the greatest common factor of a and B? What is the least common multiple?
a,b
