In △ ABC, a: B: C = () A. 1：2：3B. 1：2：3C. 1：3：2D. 3：1：2

In △ ABC, a: B: C = () A. 1：2：3B. 1：2：3C. 1：3：2D. 3：1：2

∵∵∵ A: ∵ B: ∵ C = 1:2:3, ∵ a + ∵ B + ∵ C = 180 °, a = 30 °, B = 60 ° and C = 90 °. Let a = k, then C = 2K. According to Pythagorean theorem, B = 3K. Then a: B: C = 1:3:2

If a divided by 4 / 5 equals B divided by 5 / 6 equals C, then the biggest one in ABC is the smallest one
The first answer is the best one

4a/5=5b/6=c
24a=25b=30c
The biggest is a
The smallest is C

If a divided by 4 / 3 = B divided by 5 / 6 = C divided by 1, compare the size of ABC and give the reason

A divided by 4 / 3 = B divided by 5 / 6 = C divided by 1, so a = 4 / 3C, B = 5 / 6C, so a is greater than C, C is greater than B, so a is greater than C and B is greater than B

Three fourths of the number a is equal to four ninths of the number B. what is the number B?

Number A: number b = 4 / 9:3 / 4 = 16:27
therefore
Number B is 27 / 16 of number a = 27 / 16

Let's know that the two numbers a and B are the same equation. A multiplied by 8 equals B divided by 1 / 16. Is there a proportional relationship between a and B? If so, what is the proportional relationship?

It is known that the two numbers a and B are the same equation. A multiplied by 8 equals B divided by 1 / 16,
A is proportional to B
If it's proportional, it's proportional
B / a = 8 △ 1 / 16 = 128 (certain)

Number a divided by number B (except 0) is equal to the reciprocal of number a multiplied by number B______ (judge right or wrong)

The calculation method of fractional division is: the number a divided by the number B (except 0) is equal to the reciprocal of the number a multiplied by the number B; so the answer is: √

Number a divided by number B equals 5 If B is 6, then a is ()

Because the remainder is less than the divisor, a divided by B equals 5 4, so the minimum number of B is 5; because the divisor = divisor × quotient + remainder, when B is 6, the number of a is 34

The sum of the numbers a and B is 115. The number a is equal to 8 / 15 of the number B. what are the numbers a and B?

15+8=23
A number 115 × 8 / 23 = 40
Number B 115 × 15 / 23 = 75

The number of a is 8 / 3, the number of B is 13 / 12, what is 8 / 15 of the sum of a and B?

（8/3+13/12）x8/15
=(32/12+13/12)x8/15
=15/4x8/15
=2

1 / 5 of a is equal to 1 / 8 of B, B is () more than A. if the difference between a and B is 15, then a is (), B is ()

1 / 5 of a is equal to 1 / 8 of B, and B is (60)% more than a,
If the difference between a and B is 15, then a is (10) and B is (25)
