10.
_%of 40=36
Explanation The given equation is asking for what percent of 40 is equal to 36. To solve this, we can set up a proportion: x/100 = 36/40. Cross multiplying, we get 40x = 3600. Dividing both sides by 40, we find that x = 90. Therefore, 90% of 40 is equal to 36.

11.
_% of 180=90
Explanation The given equation can be rewritten as "x% of 180 = 90". To find the value of x, we need to solve for x. By dividing both sides of the equation by 180, we get "x% = 90/180". Simplifying further, we have "x% = 0.5". To convert this into a percentage, we multiply both sides by 100, resulting in "x% = 50". Therefore, the value of x is 50.
Rate this question:
12.
_%of 140=70
Explanation The given equation "% of 140 = 70" can be rewritten as "x% of 140 = 70". To find the value of x, we can set up a proportion: x/100 = 70/140. Solving this proportion, we get x = 50. Therefore, the answer is 50.
