First, you can multiply the numerator and denominator to get like denominators: 2/5 + 1/10 4/10 + 1/10 = 5/10 which is the same as 1/2
One plus one is two. It can be expressed mathematically as 1+1 = 2.
(y+1)/5 + (2y+1)/2 = 1 Multiply through by 10 (= hcf of 5 and 2) 2(y+1) + 5(2y+1) = 10 2y+2 + 10y+5 = 10 ie 12y = 3 or y = 1/4
The two numbers that add to get negative 2 but multiply to get negative 5 are -1 and 5. When you add -1 and 5, you get -1 + 5 = 4. And when you multiply -1 and 5, you get -1 * 5 = -5. Therefore, -1 and 5 satisfy the conditions provided.
You don't need a common denominator to multiply or divide fractions.To multiply fractions, multiply the numerators and the denominators, e.g.:1/2 x 3/5 = (1/3) / (2/5) = 3/10To divide fractions, multiply the first fraction with the reciprocal of the second.1/2 divided by 5/3 is the same as 1/2 times 3/5.
The product of (3x-1)(x+5) = 3x^2 +14x -5 by multiply out the brackets

5 + 6 + 2 + 1 = 14
2(3x + 1) = 5(x + 1) Multiply out the brackets: 6x + 2 = 5x + 5 Subtract 5x from both sides: x + 2 = 5 Subtract 2 from both sides: x = 3 Check: 2(3*3 + 1) = 2(9 + 1) = 2*10 = 20 and 5(3 + 1) = 5*4 = 20.

3/(x + 5) = 2/(x + 1) Multiply both sides by ( x + 5) & (x + 1) Hence 3(x + 1) = 2)x + 5) Multiply out the brackets 3x + 3 = 2x + 10 Subtract '2x' from both sides x + 3 = 10 Subtract '3' from both sides x = 7

1 + 5 - 2 + 256576567788 = 256576567792
9/8 = 1/2 + 5/8 as multiply 1/2 by 4 to make lower number the same, i.e. 1/2 = 4/8 then 4/8 + 5/8 = 9/8 which is 1 and 1/8
