In order to write

as a percentage, we must first convert the fraction into a decimal. We can do that simply by dividing.
35 / 20 = 1.75
In order to convert a fraction to a decimal, we must multiply it by 100
1.75 * 100 = 175%

as a percentage is 175%.
Hope that helped =)
Answer:
ghhhhhh
Step-by-step explanation:
Because its not quite clear if the 5 is negative you might want to try once with a positive and once with it negative. anyway, when you only have multiplication like this, so no addition or subtraction, you can "distribute"the exponent on the outside of the parenthesis. so the first two terms become 8^(-2/3)(w^7)^(-2/3) hopefully you can figure out the rest. from here, with w if you have something to an exponent which is also to an exponent, you can multiply the exponents. so that's 7*(-2/3) which is-14/3. let me know if you have trouble with fraction multiplication. now negative exponents have something special about them. if you have a negative exponent you can write it as one over that term with a positive exponent. so the first term becomes 1/(8^(2/3)) which is 1/4.
