Question

Adam has saved $35\%$ of the $\$400$ he needs to save to buy a bike. How much money has Adam saved so far?

Answer 1

Hint: In the above problem, we have given that Adam has saved $35\%$ of the $\$400$ to buy a bike and we are asked to find the saved money so far we have to find $35\%$ of $\$400$ which we are going to find by multiplying $\$400$ by $\dfrac{35}{100}$ and then solve this multiplication. The result of this multiplication gives the money Adam saved so far.

Complete step-by-step answer:
To buy a bike Adam saved $35\%$ of the $\$400$. Now, we are asked to find the money saved so far which we are going to find by multiplying $\$400$ by $\dfrac{35}{100}$ as follows:
$\$400\times\dfrac{35}{100}$
In the above multiplication, 100 will be cancelled out from the numerator and the denominator and we get,
$\$4\times35$
Multiplying the above expression will give us:
$\$140$
From the above solution, we have found the money Adam saved so far to buy a bike is equal to $\$140$.
Hence, Adam saved $\$140$ so far to buy the bike.

Note: From the above problem, we have learnt to convert percentage into number by dividing that number by 100. For e.g. in the above problem, we have written $35\%$ of $\$400$ as multiplying $\dfrac{35}{100}$ by 400 and it will look as follows:
$\$\dfrac{35}{100}\times400$
The sign of percentage means we have to divide 100 to that number. In this way, you can remember how to eliminate the percentage sign and use it in the mathematical expression.
Also, make sure you have done the calculations properly and don’t forget to put $\$$ sign in front of the multiplication.
