What is an unknown divided by 3 times 5 and the unknown equals 1512

What is an unknown divided by 3 times 5 and the unknown equals 1512

Let this number be X
Then x / 3 * 5 + x = 1512
8x/3=1512,
So x = 1512 * 3 / 8 = 567

Five times six is thirty-six, so six times six is thirty-six?
Help answer, the best formula, thank you
The question must be right. My friend asked me this question. It seems that it was given by their teacher-

It should be 5 * 6 = (5 + 1) times 6 = 36
The formula is a * b = (a + 1) times B
Here, B = 6, then the formula is a * 6 = (a + 1) times 6
When a = 6, B = 6,
A * 6 = (a + 1) times 6 = (6 + 1) times 6 = 42

6.75 times 6.5 plus 6.8 times 2.4 plus 6.5

6.75 × 6 and 4 / 5 + 6.8 × 2 and 1 / 4 + 6 and 4 / 5
=6 and 4:3 × 6 and 5:4 + 6 and 5:4 × 2 and 4:1 + 6 and 5:4
=6 and 5 / 4 × (6 and 4 / 3 + 2 and 4 / 1 + 1)
=6 and 4 / 5 × 10
=(1 / 7-5) × 10
=7 × 10-1 / 5 × 10
=70-2
=68

How many centimeters is 11 "H x 13.8" W x 4 "d multiplied by how many

"Is inch, 1 inch = 2.54 cm
11''h x 13.8''w x 4''d = 27.94 cm x 35.05cm x 10.16cm

13 times (5 / 26 + 5 / 22) times 4 / 11

13*(5/26+5/22)*(4/11)
=65*(1/26+1/22)*(4/11)
=65*(11/286+13/286)*(4/11)
=65*(24/286)*(4/11)
=65*(12/143)*(4/11)
=65*(48/1573)
=3120/1573
=1 (1547 / 1573)

How much is 4 / 7 times 2.1?

Six fifths

() () 7 times () equals 2 () 512

297×96=28512

2 / 9 times () is 7 / 2

2/9*X=7/2
X=7/2*9/2
X=63/4
The answer is 63 / 4

There is a number P divided by 10 over 9, divided by 9 over 8, divided by 8 over 7. How many such numbers are there between 100 and 1000? How do you find them?

The number P divided by 10 is more than 9, divided by 9 is more than 8, divided by 8 is more than 7
The number P can be divided by 10, 9 and 8 by adding 1
So the number P is the common multiple of 10,9,8 less than 1
The least common multiple of 10, 9 and 8 is 360
therefore
There are two such numbers between 100 and 1000
namely
360－1＝359,
360×2－1＝719
