Question

Using the simplified expression 1.2p, explain what it means to have 20% more of a given quantity 

Answer 1

If we use the expression 1.2p, where p stands for the given quantity, we can calculate 20% more of the given quantity. First, 20% is the same as the fraction 1/5. To find 20% more of the given quantity, we must multiply the given quantity by 1.2, which is the same as 1 + 1/5. Using our expression 1.2p, we can find 20% more of the given quantity by multiplying it by 1.2. Mathematically, the answer would be 1.2p * 1.2 = 1.44p. Therefore, to have 20% more of a given quantity using the expression 1.2p, we would multiply 1.2p by 1.2, resulting in 1.44p.
