Question

siobhan scores 4 out of 10 marks in a science test . what is her score as a percentage ?

Answer 1

Answer:

40%

Step-by-step explanation:

Remember that a percent is out of 100 parts

4/10 can be multiplied by 10 on each side to get 40/100, or 40%

Another way is to do 4/10=x/100 and cross multiply, getting 400=10x, dividing by 10 on both sides, and having x=40% (don't forget the symbol)
