Answers

Answer 1
Answer:


Fourteen is 28% of B) 50

Why, you ask? Let's see -

Let the unknown number be n, for 'number'.

Let's put the unknown n next to 28%

.28n% = 14

(Think, what times .28 equals 14? Look below to find out! ↓ )

Let's now do the opposite of the actual equation - divide the two known numbers by each other -

.28 ÷ 14 = 50

When in doubt, check your answer:

To check this, we would do the opposite - Multiplication

Multiply .28 by 50 to get 14 (At least you should get 14)

.28 × 50 DOES EQUAL 14! We were right! :D
