These are all very simple questions. You'd better read the book

73 out of 9, 90 out of 15, 51 out of 17, 47 out of 4, and 63 out of 8 are changed into false scores
J urgent

It should be with scores
73 out of 9 = 8 and 1 out of 9
90 out of 15 = 6
51 out of 17 = 3
47 out of 4 = 11 and 3 out of 4
63 out of 8 = 7 and 7 out of 8

Fifty one out of seventeen into fractions or integers

51/17=3

The sum of a divided by B and C equals ()

The sum of a divided by B and C is equal to (A / (B + C))

If A-B divided by a + B equals 3, then what is 2 (a + b) divided by A-B

A-B divided by a + B equals 3
a-b=3(a+b)
2 (a + b) divided by a-b
=2(a+b)/3(a+b)
=2/3

2 / 3 divided by a / 5. When the quotient of a () is equal to 2 / 3, when the quotient of a () is less than 2 / 3

A=5,a>5

If 1 equals 5, 2 equals 10, 3 = 15, 4 = 20, then how much is 5?

Because it is said at the beginning that 1 is equal to 5 should be an assignment, which has nothing to do with the middle, so 5 = 1

If 1 equals 5, 2 equals 10, 3 equals 15, 4 equals 20, then what is 5 equal to?

1

Find the rule: 1 = 5,2 = 10,3 = 15,4 = 20,5 = what?

Of course, 5 = 1, because the title is 1 = 5, which is obviously a sharp brain turn

Calculate 1 × 3 × 5 + 2 × 6 × 10 + 3 × 9 × 15 + 4 × 12 × 20 + 5 × 15 × 251 × 2 × 3 + 2 × 4 × 6 + 3 × 6 × 9 + 4 × 8 × 12 + 5 × 10 × 15 =___ ．

1 × 3 × 5 + 2 × 6 × 10 + 3 × 9 × 15 + 4 × 12 × 20 + 5 × 15 × 251 × 2 × 3 + 2 × 4 × 6 + 3 × 6 × 9 + 4 × 8 × 12 + 5 × 10 × 15, = 1 × 3 × 5 × (1 + 8 + 27 + 64 + 125) 1 × 2 × 3 × (1 + 8 + 27 + 64 + 125), = 52
