What is 2 over 5 plus 1 over 10?
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
1 plus 1 plus 1 plus 1 plus 1?
One plus one is two. It can be expressed mathematically as 1+1 = 2.
Bracket y plus 1close bracket divided by 5 plus bracket 2y plus 1close bracket divided by 2 equals 1 Could anyone help sorry but was not allowed to use punctuation?
(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
What adds to get negative 2 but multiplies to get negative 5?
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.
How do you do common denominator division?
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.
