How do I figure out fractions?
To work out a fraction of a number, all you need to do is divide that number by the denominator of the fraction, then multiply your result by the numerator of the fraction. For instance, if we wanted to find out what 3/8 of 24 is, we would divide 24 by 8 (the denominator of the fraction).
What is the answer 5×5?
Using order of operations or PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction, from left to right) -5×5 goes first resulting in -25. You’re equation will be: 5–25+5. Using order of operations further solve: 5–25= -20. The equation will now be -20+5 your final answer will be -15.
