Answer: 5/(2)^9
Step-by-step explanation:
(40^7)/(2^30 x 25^3)=
(2*2*2*5)^7 / (2^30 x (5*5)^3)=
(2^7 * 2^7 * 2^7 * 5^7) / (2^30 x 5^3 * 5^3)=
(2^(7+7+7) * 5^7) / (2^30 x 5^(3+3))=
(2^21 * 5^7) / (2^30 x 5^6)=
2^(-9) * 5^1=5/(2)^9

3/4 = x/400, and we are trying to find x.
Multiply the numerator and denominator of 3/4 each by 100 to make the denominator equal 400. This gives 300/400. So, 300/400 = x/400.
Multiply both sides of the equation by 400 to cancel out the division. This gives you 300 = x, so 300 parents said yes to the survey.
