What is 1/3 of 15
The word 'of' means multiplication so we need to multiple 1/3 by 15. Remember that whole numbers can be written as fractions by putting them in the numerator over 1. So 1/3 x 15/1, we multiply the numerators then we multiply the denominators We get 15/3, now we can just divide 15 by 3 since the fraction bar also means division. 15 divided by 3 is 5
Let's use the distributive property to expand this. We need to multiply 8x by each of the terms in the parentheses. 8x times 3x is 24 x^2 plus 8x times 7 is 56x so the answer is 24x^2 + 56x
