use the tens place to multiply by 2, then use the number to subtract the ones place.The answer can be divided by 7, if not it will be 0.use 490 as an example.9x2=18.18-4=14.14 divided by 7 is 2. so 49 can be divide by 7
49 = (±7)2 x2<=49 => -7 <= x <= 7
2x/7 = 11 Multiply both sides by 7: 2x = 77 Divide both sides by 2: x = 77/2 = 38.5
4x+5=6x-7 To solve this, us the 5 steps for solving an equation: 1. Eliminate parentheses/Distribute Not applicable. No parentheses or need to distribute. 2. Add like terms. Not applicable. No like terms. 3. Eliminate the variable on one side or the other. 4x+5=6x-7 Reverse the sign of 4x, making it -4x and put it in on the left side and the right side. This makes it: 4x-4x+5=6x-7-4x Now add like terms 5=2x-7 4. Eliminate the constant term on the side of the variable. 5=2x-7 Reverse the constant term on the side of the variable (-7 becomes +7) and put one on each side: 5+7=2x-7+7 Now add like terms: 12=2x 5. Solve for the variable by dividing both sides by the coefficient 12=2x This rule means that whatever the number is before x (in this case, 2), divide the other side by it. 12 divided by 2=2x divided by 2 And solve 6=x
42 divided by 7 times 2 is equal to 12.

7/12 divided by 2/3 equal 7/12 times 3/2 (We invert and multiply when dividing fractions.) 7/12 times 3/2 equals 7 x 3 / 12 x 2 (Multiply the numerators together and multiply the denominators together.) 7 x 3 / 12 x 2 = 21 / 24 Now find the lowest common denominator. 21 / 24 = 7 / 8

80 divided by 7 and 1/2 = 10 and 2/3 80 divided by 7/12 = 137 and 1/7
7 and 4
10/7 ÷ 2 = 5/7
7/12 ÷ 5/6 = 7/10 or 0.7
It is 2/7
Expressed as a proper fraction in its simplest form, 6/7 / 12 = 1/14 or one fourteenth.
