Question

Jonathan has a collection of 400 marbles. Blue marbles make up 17% of his collection. How many blue marbles does Jonathan have?

Answer 1

17%=17/100 = 400 marbles
17% of 400=blue
17% of 400 or 0.17*400 = 68 blue marbles.

Hope this helps :)

Answer 2

No. of total marbles = 400
percentage of blue marbles = 17

=
`(17)/(100)` × 400
= 17×4
= 68
