Answer:
(a) 14
(b) 80
Step-by-step explanation:
(a)
We need to find 35% of 40. First, we need to note that the word "of" in the mathematics world means "multiply", so "35% of 40" actually means "35% * 40".
Percent is just "out of 100", so 35% is 35/100. Now, we have:
35% * 40 = 35/100 * 40 = 0.35 * 40 = 14
The answer is thus 14.
(b)
We need to find 95% of what number is 76. Again, we see that "of" means "multiply". Another word to pay attention to is "is", which means "equals".
Let's say the "what number", or unknown value, is x. We can then write:
95% * x = 76
Remember % is "out of 100", so 95% = 95/100. Then:
95/100 * x = 76
0.95 * x = 76
x = 76/0.95 = 80
The answer is thus 80.
